I'll be fine with .38 spl.

Yes you will and so would I. I have them in my 642-2 which could also take Plus P. I sleep well at night. Those soft cast BB 20C 158s would be an acceptable PD round in most cases.

Standard Pressure Short Barrel Low Flash Heavy .38 Special Ammo - 158 gr. Soft Lead SWC-HC (850fps/M.E. 253 ft. lbs.) - 20 Round Box

Due to customer demand, we've developed this defensive 38SPL ammo. Our customers wanted some devastating 38SPL loads that would fill the following criteria.

1. It won't hurt older/fragile/alloy revolvers. (Non +P)
2. Is effective as a "fight stopper" through the use of proper bullets.
3. Is more powerful than typical/standard, weak 38SPL ammo.
4. Generate much less recoil than our +P 38SPL ammo.
5. Is flash suppressed

A 340 with full size Monogrips and these would be a "pussycat".

Finally! My range report:

I finally made it to the range today. It's a long story why it took so long, maybe another time on that story. So I brought both my 340PD and 43C (a .22 in 340 Centennial clothing), but not the M&P because I may return the M&P to Smith and Wesson to fix some factory defects. I figure the 340PD is close enough in weight to the M&P that the range reports would be very similar.

With all the talk surrounding the brutality of these scandium devils I figured I'd buy the heaviest, meanest ammo I could find to ensure an honest appraisal about whether it's truly that brutal, or as a friend said, "vicious" to shoot. The good news, shooting the 11 ounce Smith and Wesson 340PD with titanium cylinder was not "vicious". The bad news, it was harsh, maybe even brutal when firing factory new Remington Express 158 grain full power .357 Magnum ammunition. Unfortunately my range has only one pistol distance, 25 yards, and I was only getting 3 out of 5 shots in a torso sized area. I will not be so quick to attribute the poor accuracy to the recoil of .357 Magnum, because I intermittently did a lot of dry firing at the 25 yard target, observing the sight picture while doing so to assess the matter.

I observed that what seemed like an incremental movement of the muzzle while pulling the trigger translated to a significant amount of movement across the paper target 25 yards away. Those of you with the CT laser probably have a better estimation of the significance of this. I believe this gun will certainly benefit from some performance shop work on the trigger and trigger pull. My theory is borne out by the fact that when I shot my 43C which has a much better DAO trigger pull than my 340PD, there were a heck of a lot more holes on the torso sized piece of paper! Of course the XS Standard Dot front sight on the 43C is a great improvement over the red ramp blade of the 340PD and my PD will be getting an XS Tritium Standard sized or possibly Big Dot sight. I should also say that when I staged the trigger of my 340PD for single action firing, my groups improved but I shot mostly DAO at the range today.

Another important note, I would fill the 340's cylinder with 3 live rounds and 2 empties, and sometimes 2 live and 3 empties to observe if there was any flinching when I shot and I believe it would be a benefit to all shooters to experiment with this.

Unfortunately, I did not have a chronograph. I did bring 10 rounds of the very expensive Remington Golden Saber .357 Magnum ammo, 125 grain, and I will say that while the recoil was not as harsh as the full power 158 grain ammo, it was stout, buckle up! Personally I don't like the idea of the Golden Saber Mag ammo as I've read many chrono reports and out of the snub barrel they only achieved an average of 1030-1090 FPS velocity with the 125 grain bullet. Sounds wimpy to me, but let me tell you, if God forbid my hand is forced and there ever has to be a human being at the other end of my 340's muzzle, if the wallop that I felt in my hand from the Golden Saber Mag is gonna be narrowed down to a .357 sized punch for him, he's in trouble. The recoil was stout. I did not fire enough rounds to know if it was punishing.

Speaking of punishing, the area around the web of my hand is a little swollen, a little tender, but I'll live. I fired 27 rounds of full power 158 grain Magnum ammo and 10 rounds of the Golden Saber, though my first five shots out of the gun were Golden Saber to "break in the gun". No joke, I wanted to "break in" the gun. I've seen enough photos and reports of "blowed up" Smith 340's and read reports by alleged metallurgists that "because the barrel that screws into the alloy frame is steel and their heat coefficients(?) are different, it results in a 'blowed up'" scandium alloy gun. Fact or fiction, I thought I'd just warm up the gun with milder rounds first.

On a side note about a different gun, I once read that full power .357 ammo fired through my much admired Smith and Wesson Model 66 K frame four inch is brutal. To test this theory I fired ONE round (didn't want to wonder whether the holes on the paper came from the 66 or the 340PD) out of my 66 and it was a pussy cat, muzzle flip, yes, but a pussy cat. It has standard square butt wood stocks, the small ones, not the large target stocks they usually come with. I also have a Tyler T Grip Adapter fitted to it, the gun is a dream to shoot set up thus, even though I offer an assessment based upon only one round. I have fired my four inch 19 with full power Mags but that was years ago, and I don't remember it being punishing either.

I fired 37 Magnum rounds out of my 340PD today, but I counted out over two hundred .22 caliber rounds fired from my Smith 43C. If you can afford this little gem, BUY IT, it'll no doubt pay for itself in ammo cost savings to acclimate yourself with the basic mechanics of the 340 (but never the recoil). I easily could have remained at the range firing another one to two hundred rounds of .22 and probably another 20+ rounds of Golden Saber ammo out of my 340PD were it not getting late. I could have possibly finished off the box of full power .357 ammo but it would have been a continuation of my "sucking it up" through the punishment, hate to admit it but full power ammo was punishing though it did not stop me from firing full power ammo on and off throughout my stay at the range.

To address whether the recoil is too impractical for fast follow up shots, I still say that if I'm carrying my 340 and I believe my life will end if I don't shoot, I want all the power I can get, or better to say all the power I can skillfully handle. I must try full power 125 grain Magnum ammo, I've been told the full power 125 grain is not as harsh as the full power 158 grain ammo. I will find out for myself. Yes, muzzle rise was there, but I could not actually observe to what extent, and I was becoming faster with follow up shots but I need more practice.

I would certainly like to try Buffalo Bore short barrel low flash tactical .357 ammo of the 158 grain variety as I've always had a hunch this would be the ideal carry ammo for the 340 series guns, or I'd stick with the Golden Sabers. When I feel the wallop I get in my hand from a Golden Saber, it inspires within me confidence, confidence that someone's gonna get hurt when this thing discharges and it ain't just gonna be me...

Method of gripping these guns: I've seen it mentioned on this forum and elsewhere, Jerry Miculek's videos on proper grip for a Smith J frame revolver. Find them and watch them, I'm satisfied that this gentleman knows what he's doing!! I've seen plenty of youtube clips where the 340 flies up out of the SUPPORT hand when firing... not gonna happen when you adhere to Mr. Miculek's recommendations. Thanks to Mr. Miculek I do believe "faster" follow up shots are possible using medium to full power Magnum ammo and I had a lot of control while firing my PD with full power 158 grain Magnum ammo, and I also had plenty of people looking over at me or making comments of astonishment about "what the heck are you shootin'...?" to remind me that Mr. Miculek's teachings were doing a heck of a job keeping an explosive beast under control. Hell, one fellow praised me more than a couple times and profusely just because I keeping 3 out of 5 rounds on paper at 25 yards!! Thank you Mr. Miculek!! Imagine being praised despite misses!!

All in all, I thoroughly enjoyed my range session! You're thinking: "ENJOY???" YOU'RE DAMNED RIGHT I DID!!!!! Yes, it was punishing, yes there was pain, but nothing you can't deal with. No, I would not want fire ten consecutive rapid fire rounds of full power ammo if I had two 340PD guns loaded and ready to go, but yes, I did in fact truly enjoy blasting away with this miniaturized monstrosity. It is an expensive and brutal little gun. Is it worth it? For most, probably not, for me, I have zero regrets...

Again, thank you DAdams for this forum and thank you to all who contribute to this forum!! Happy Shootin'...!!!

By the way, I included a photo of my 340PD, 43C, both still dirty after their session at the range a couple hours ago, and my M&P.

I wanted to addres another subject, night vision and flash...

We've all read that one drawback to the .357 Mag ammo out of a snub is the amount of flash and subsequent loss of night vision. Tonight I remembered to try an experiment I've been wondering about for the past six or so months. In all my life I've never lived in any city or town that is actually dark at night. As I walk around my town at night, I've got the glare from street lights, lawn lights, store lights, passing autos, and more. Even late at night when it's only storefront and street lights, it's bright enough that I've thought the loss of night vision would not happen from the flash of a .357 Mag.

So tonight, I grabbed my camera, fresh batteries, stepped outside in an area of typical late night illumination, pointed the camera at my face, held out at arm's length, I did not stare directly at the flash, I stared straight ahead a few inches above it, focusing on human sized objects around me, and flashed away repeatedly. Believe it or not, my vision for a quick follow up shot was not impaired, I was not blinded for seconds. I saw maybe a dark ghost of the flash for a fraction of a split second, but it wasn't a blinding imprint of the flash, just a dark split second ghost. I'd like to spend more time with this experiment, but one thing is certain, this loss of vision or being blinded by flash is nowhere near what I thought it would be from what I have read. I could be wrong but I believe the flash from a camera is brighter than the muzzle flash from a short barrel .357 gun.

As mentioned, it was only a two minute experiment, I need to spend more time with it, but I hit the flash while it was pointed at my eyes several times one after another, about a second or two in between as the flash built up juice, and I easily saw everything in front of me at night among the street lights immediately after the flash.

This is just food for thought for y'all, maybe a jumping off point for your own experiments on the matter. It satisfied my belief that flash blindness is heavily exaggerated, what I experienced I would not consider flash blindness at all. Again, this was with a camera flash, and I'd like to try this with an actual gun if our range is lit similarly to our town at night and allows evening sessions.
 
Thanks for that, Mister_Smith.

Many claims in the firearms world are grossly exaggerated, such as those that claim a shotgun slug will blow through any body armor or at least break all the wearers ribs (it won't even knock someone wearing level IV rifle plates down, much less break bones), those that claim shooting any handgun indoors without earpro will make you deaf for hours (not true, I've done it with a .40 S&W in a 200 sq ft room and it didn't even make my ears ring), and now apparently that the flash from a .357 mag will make you blind!

Basically, a lot of people don't want to admit that the only real reason to carry .38 instead of .357 is that they can't handle the recoil. Not saying it isn't a valid reason, but let's face it, it's the main one.
 
Thanks for the report!
I will be going out tomorrow to shoot my 340....but mostly my new Glock 26 Gen 4!
I like to shoot the expensive stuff through my 340...because I don't shoot it often...and want to replicate the POA/POI as much as possible.
I shoot Speer Gold Dot short barrel 135gr .357 mag
or
Buffalo Bore 158gr .38+P

Nice write-up Mr. Smith and a great contribution to the thread and for those who may be considering a 340/360. I suspect at a more reasonable distance 7-10 yards, your proficiency would appear "mo better". ;)

I am not convinced that .357 is necessary in these light weight snubs and certainly for many it is more tolerable to run Plus P or even standard .38 spl, still preferable to a .380 85 gr.

I know for some the battering delivered by said revolvers is more than they can bear. Good for the resale market if nothing else. If using a revolver for HD or while traveling the K Frames or L Frames make ideal companions.

Thanks again for sharing your experiences.

If ... no, wait, when ... I acquire a 340 due to the quality differences over other SW airweights - which due to improvements in my professional existence, may be sooner than I expected (just have to see) - I'll feed it some hot .38 spl and save the .357 mag rounds for a heavier revolver, right now a 65. (That could change, too.)

Good to see sanity in this group. :cool:

Good for the resale market if nothing else.
So, I'll check back here when I'm ready to purchase.

Smoke'm if you've got 'em.

Our broken future is all that we hold
 
@Nemotacyst:

Do you realize if you had bought a 340 when you first said you were going to, it would have only cost you about $.04 per day? ;-)

Just joshing - you make surprisingly relevant posts considering you don't own the gun... ha!

FT you just made my day. That's a good one. :D

Actually I ran the numbers and at today's price (Bud's) which is higher than 5 years ago amortized over 5 years, works out to be 38 cents per day. :cuss::eek:
 
Question for 340PD owners

For those who own a 340PD with the titanium cylinder, if you bought your 340PD new, you noticed that the titanium cylinder was fairly tight. After your first session or first few sessions shooting full power .357 Magnum ammo (or .38 Special for that matter), did you notice that the cylinder became observably more loose? I did not notice it til this week but after my first and thus far only range session with my 340PD, the cylinder rattles when I shake the gun, it did not do that when it was new and unfired, trust me, I checked for rattle before I bought it, that's a sore point with me, rattly cylinders. I guess I expect these alloy guns to loosen up a bit with use but I was just wondering what your experiences were. I have a Smith 686 and the cylinder is as tight as it was 22 years ago when I bought it new, though I admit I probably have no more than 200 rounds through it, but some were fire walled maxed out hot loads, according to my buddy who loaded them as hot as the book allowed (out of a heavy 4" L frame the recoil was not worth mentioning).

For what it's worth, the cylinder on my 340PD now rattles about the same as the cylinder on my new, never fired 340 M&P. I've handled a few M&P's and they seem to come with cylinders that are a little looser than 340PD guns and looser than what I'm used to on older Smiths. My old and often fired Smiths, both .38 and .357 do not rattle as much as my new 340 M&P nor my 340PD which now has only 37 rounds through it, all .357 Magnum.

I am curious to see if another range session loosens the cylinder up even further (I hope not) but range sessions with this gun are quite painful, in the wallet I mean!! You thought I meant painful to my hand, huh... admittedly the recoil is severe but if anything hurts, it's the cost of .357 ammo!!

I thank you for your responses in advance!! Thank you!! :)
 
No rattles from my M&P 340 when empty. Loaded, yes, but that is the rounds in the cylinder. If I move the cylinder back and forth, there is a (very) little play but not enough to rattle when shaken. No play whatsoever fore/aft.

I only have roughly 300 rounds through it and perhaps 25 of those .357, so it is barely broken in.

Maybe due to the fact that it is almost 5 years old and SN DAW 26XX?

Maybe mine doesn't rattle because it has a lock. ;)

Was able to pick up my 340 M&P while on leave from Afghanistan. I went to the range and brought a box of .38 special and .357 magnum, as well as a box of my carry load Hornady Critical Defense 110 gr +p .38 special. The 340 is controllable with the standard pressure and +p .38, but DAMN.357 is punishing. I could only run one cylinder through it. I will be sticking to .38 for my carry load.

I bought my M&P about 6 months ago anticipating the arrival of summer. I also purchased a LC9 as a alternate. I made it a point to fire full load .357 thru it at the range and a number of .38s. I actually think the .357's are a blast to shoot. I carry it in my right rear pocket with Speer short barrel loads. With a speed loader in my front pocket and the M&P in the rear, I hardly realize it's there. If the SHTF I won't be thinking much about recoil and the blast will probably blind both of us temporarily. I bought it with the CT but found I'm quite accurate with the front sight of this handgun. Meanwhie, the LC9 sits in the safe.....
 
New Toy!!

Finally found a no lock 340 M&P-wow! Nice piece, although it is "heavier" than my now gone 340PD, however. now I can shoot light loads. I did get it and take it home!
I liked my 340PD and could hit pretty good with it although it required full concentration (as all guns should) to fire it fast and hang on to it with full house loads.
Range trip and maybe a pic or two coming up soon.

Been working on breaking in my new Glock 26 Gen4 lately...
and every time I am at the range, I also shoot 3 or 4 cylinders full of .357 mag or .38+P from my 340.

Last range session, I shot a box of .38 special reloads...130gr....just real mild loads, and had a blast with the 340!

I also have been shooting more of the Speer .38+P Gold Dot, and finding that it is much more enjoyable for practice....and probably a great round for carry.
BUT....
all those .357 magnum Speer Gold Dot that I already bought....are what I am primarily loading when I carry.

The Glock 26 is....a Glock, which means it is boringly dependable and great for CCW....
but the 340 goes with me when jogging, dressed up for dinner, or when close contact with friends and family (hugs, hugs, and more hugs) is expected.

Just wanted to keep this thread alive, and share how much I appreciate my 340!

Did some shooting with my 340 yesterday...

I am slowing getting more proficient with it.....slowly!

I am working hard on drawing from under a concealment garment while moving "off-line" and then "engaging" one or more targets.

From about 6 yards out, I am able to deliver all my shots in a center mass area, with nary a wide flyer!

I shot some from 20 yards out, just for the challenge, and......my hits were grouping tightly in a vertical line.....but off to the right....:eek:

I find that the 340 is (more and more) becoming my go-to carry weapon, so I need to get more proficient with it.

I am pretty smooth at using a speed strip to reload...but the word "speed" should be left out of the equation.

Anyone have an idea of what speed loaders work well with the 340?
Do they clear the stock rubber grip?

Anyone tried the VZ grips yet?

How about holsters? What are you all using?
I am using a Remora, and love it....but loops or clips would be a better alternative.

Let's get this thread pumped up again, get some fresh info and pics!

Nice pics over here. :)

Haven't been around in a while.

(Standard disclaimer: not a 340 owner, just a wannabe and friend of the thread founder.)

The 340 is controllable with the standard pressure and +p .38, but DAMN.357 is punishing.
I could only run one cylinder through it. I will be sticking to .38 for my carry load.

OK, so I know this is heresy for pocket carry, but I don't, so ...

What would this lil' beast be like with a set of full Hogue monogrips on it?

My 642 wears a set, and double taps with +p is like riding a pony.

I think the full Hogue monogrip would be great for comfort at the range...

but I like to practice with my revolver set up exactly as I will carry it....
and I ain't carrying it with those big suckers on it! :what:

Big butts are in, though....:neener:
