S&W J Frame?

A model 36 and a model 640 have a bit of weight difference between them.


Maybe not as much as between the 640 and 642... but enough for it to not really be an apples-to-apples comparison. Especially for pocket carry where every ounce counts.

That's a non issue, if you can't pocket carry a j frame steel or airweight then you need a better belt pure and simple, I know several people myself even once carrying a loaded glock 26 in the pocket without any issues.
 
It's hard to respond on the weight issue. Some people say a steel J frame is too heavy for pocket carry. Others say they can't pocket carry any J frame.

Still others find the weight no problem.

Below is one of my pocket carry guns. An all steel Model 49 which probably weighs as much as a 940. I find it no problem to pocket carry, and have been pocket carrying J frames for three years. No one has ever noticed.

As for crimp jump, I'd just test the practice ammo you use, and especially your SD ammo and you should have no trouble finding a factory brand of both that has no problem. Only a small minority of factory loads from known manufactures are a problem.

I have an LCR 9mm revolver which is lighter than the 940 and the only crimp jump problems I've had were with cheap reloads.

I have pocket carried my Model 638 in a Desantis Nemesis holster and it's a piece of cake. Not so much so with it's all steel Model 649 brother. With that I go with a Desantis SOF-TUCK IWB holster.

Well I guess it's settled, then!

Thanks for clarifying.

Pocket carry is very dependent upon both type and size of pants. Skin tight jeans and lightweight dress slacks pose more problems than baggy jeans or cargo pants. I can pocket carry a G26 and even a Springfield XDs with the right pants, but when wearing a dress suit I might only be able to handle a KT P32. Most days it is either a Kahr PM9 or a S&W 442 for me. YMMV.
 
I believe there was a rimmed 9mm once made for Charter arms revolvers to function like the .45 auto rimed to enable extraction in a weapon really designed for rimmed ammo but it is no longer manufactured. One should be able to load 9mm ammo in the cylinder designed to hold it and head space in the chamber. You would have to shake the cartridge loose to extract it or poke it out with a pencil or some other rod if not using a clip of some sort.

I believe that was the 9mm Federal. I have one or two in my cartridge collection, but I have never fired one of those rounds. They are damn rare finds now, but you never know what you'll run across if you look hard enough....
 
So Im a pretty young guy, live a pretty boring life as an insurance agent and I shoot USPSA and have been carrying a makarov for a few years and Im looking to get hooked into something I can have as a pocket gun since I live in Indiana and have a permit but am near the Illinois border and I am looking to get a S&W 940 for a sweetheart deal from a friend's relative's estate sale.

I really enjoy shooting snubs and given that I already purchase something on the order of 2500-4000 rounds of 9mm ball a year for USPSA a J frame in 9mm really logistically makes alot of sense for me.

So with a smith and wesson 940 or 941 is there any issues? Does it have the tabs to hold 9mm without moon clips or do they take moon clips? Is there any ammo that has issues with bullet pullback? Would it instead be a better option to have a .357 J frame and get a gunsmith to convert the cylinder and cut it for moonclips?

Never heard of a s & w 941, but the 940 is a better choice imho over the .357 j frame as it gives up very little velocity loss compared to the .357, recoil is much lighter as is muzzle blast. Moon clips can be had for fast loading/reloads, but you can shoot them w/o the clips & just punch them out. S & W told me decades ago that I could shoot a limited amount of +P, but not tu use any +P+ (I did try some though & they tied up the action as the fp pierced the primer). Never experienced any bullet pull, but I have not shot it in about 20 years.
 
I got a 940 when they first came out. +P ammo would lock it up so tight the armorer had to beat it open with his babbitt bar. I got rid of it and picked up a 640 magnum when they came out.
Mine did the same thing. The firing pin was too sharp & pierced the primers, locking up the gun. Sharp taps on the gun would jar the fp out of the primer. S & W fixed it on their dime decades ago.
 
I have pocket carried for years. It depends on the pants and belt for me. The top gun a 7 shot 357 Taurus has been carried in a pocket. It weighs 2 pounds loaded. I don’t normally carry it that way but if I need to it’s possible. The 442s or the bobbed 37 make better pocket guns. They are half the weight and a bit smaller. The 36 with hammer could work in a pocket but the hammer makes it a pain to draw. So, daily I carry the 442 with boot grips in my pocket. One of the others backs it up in my belt. 6C8DF8DF-A85B-424C-9075-C7CD110DCDCB.jpeg

Perry Suspenders slip on your belt and keep your pants up.
No matter whether it's pocket, belt, or IWB carry.
The noble and notable " rc model " steered me and others toward Perrys.

In terms of ammo, personally Im going to get 147 grain flat nose USPSA/IDPA "Puff loads" in bulk to both shoot in matches and to carry in a gun like this. With the small amount of fast burning powder I get the most juice out of the short barrel, less recoil, and with a heavier bullet at lower velocity just from a physics standpoint less crimp jump.

And yeah I know ball ammo isn't all that great but in a short barrel I would rather have a round with a flat nose that punches straight through then have a round that opens up to soon and doesnt have the energy to penetrate well. Also I live up around chicago and it gets cold. A big dude in winter clothing and a less then ideal target presentation is something that I am much more likely to face then a guy in say Texas with the vatos running around in T-Shirts or less lol

I think you can do better than that, not that I disagree with your reasoning. Here are some tests of HP from 2" barrels, some of which look pretty good.
 
my latest J-frame is a md 34 rb with a 4" barrel in .22 cal. eastbank.
