One of the best 22 WMR I believe

[357smallbore]

Bought this off the auctions 7-8 years ago. My 1975 HIgh Standard Sentinel MK-IV in 22 mag is one of the best 22 mag revolvers made. Love shooting this gun. Plenty reliable, accurate as you'd want for plinking of self defense. The gun is deeply blued with a pinned barrel. This is a rare top quality piece in my opinion.
And topping all that off, it's an easy carry gun.

Very cool!
I'd love to have Mk4 in .22LR. I fixed up an original Sentinal for my buddy who found it rusted shut on top of a refrigerator at his FIL's hunting cabin. It struck me as a slightly incomplete prototype that beancounters ordered into production anyway, lol. Some nifty ideas, but room for improvement- and a real PITA to detail strip!
I believe they rectified some of the worst issues with the MK4. Nice gun.

I've never seen one of those, very cool.

 

[sparkyv]

Me too. Very cool, indeed!

When my Dad passed away my Mom gave me his High Standard Sentinel Mk IV .22 Magnum. It had a 2” barrel and someone obviously dry fired the heck out of it and the cylinder was all chipped up. My Dad had gotten it ‘used’.
The funny thing about me receiving this gun was my Mom called me and asked “Which one of you Dad’s guns would you like to have?”
I told her I wanted the S&W K22 with an 8 3/8” barrel. For some reason she thought I wanted the High Standard and she gave the K22 to a friend of my Dad’s.
Oh well…

Anyway, I bought a cylinder for it and a 4” barrel. I got real lucky with the timing of the cylinder. I also bought the used grips that are on it now.
My sister needed a gun for HD. She has arthritis in her hands and can’t manipulate a semiauto so I gave her the High Standard until we can get her something with a bit more juice.
Please don’t turn this thread into a discussion of .22 Magnum as a defensive weapon.
Besides, she never received anything that belonged to Dad so I gave her the High Std.
Cartridge cases are a bit sticky in the chambers so I have the gun now to polish the chambers for her. I took these photos of it and the original barrel.

Neat piece of hardware. I'd definitely like to play with one of those.

A .22 WMR in the hand beats a .45 ACP in the safe, every day and twice on Sundays.

Good save on that gun.

Always, my .22 WMR revolver other than a Ruger Convertible is a blued 4" Colt Trooper MKIII.

 

[cfullgraf]

Nice revolver.

I've gotten into 8-3/8" S&W K frame revolvers and I stumbled into an 8-3/38" Model 48. I bought it and then bought a 4" and 6" versions from the S&W Classic series Model 48.

 

[Fyrstyk]

I have a S&W Model 18 with 4" barrel and .22 mag and LR cylinders. The mag cylinder has been on the gun since i bought it. It is accurate (1"@25YARDS) and it has taken a few called in coyotes for me. A great woods carry gun where there aren't any large predators except the 2-legged kind.

 

[CajunBass]

I've always wanted one of those, but never cared for the 22 magnum cartridge. I'm not sure if they made the same gun in 22 LR or not, but if they did, I've never seen one, or I'd have bought it. I've owned several of the older High Standard Sentinels and liked them quite a bit.

That MK 4 has a sort of "Mini-Python" look to it that I always liked.

Try using a Flex Hone and some light oil. Chuck the hone in a drill press (best), dribble a bit of oil and give each chamber several passes.

They have two grits, and can be bought off Amazon.

I have had to hone several of my .22 LR and .22 WMR revolvers due to sticky (some near-impossible) extraction. Worked every time. (I wasn't aware the ones I had were marked .22 wmr until a THR member pointed it out, but they worked just fine on .22 LR. )

Cool little guns!

Stay safe.

I lusted after one of those decades ago but whenever gun money came available I bought something else. Nice catch.

 

[doubleh]

Riomouse's idea will work just fine. On the other hand I use a bore mop with fine Clover valve grinding compound to do the same thing.

Made a quick Colt Trooper MKIII .22 Mag video for Christmas.

Colt Trooper MKIII .22 Magnun - @NewWaveFirearms Safe Shorts

Today's gun is Colt's .22 Magnum chambered Tropper MKIII. A silky smooth and royally blued 4" six-shooter that is just the perfect Christmas stocking stuffer...

357smallbore, That is a beauty! It's hasn't been a priority, but I've kept an eye out for a clean MK-IV .22 WMR with 4" barrel and adjustable sights for a long time. The very few I've seen were rode hard and put away wet. Don't let that nice example get away from you..

It's mine. Had it awhile. Love shooting and carrying it.

This 1959 no-dash model 48 led a hard previous life, but it gained back some of its dignity with a hard-chrome plating job by Ron Mahovsky not long ago.

 

[fallout mike]

Nice gun! I have never owned a quality .22 revolver. I have been getting the itch for one recently. I will probably buy a older Smith but now may look at your model. I have never really been into these .22 revolvers so my knowledge of them is probably the least of all my gun knowledge.

 

[JERRY]

While not meant for the same usage I'm really liking my 351C.

Nice pat ! I too have a snub version , with both .22 Mag and LR cylinders in great condition . How ever I have found the snub shoots way high ,with either cylinder but more with the WMR cylinder. There is not enough rear site correction so I am contemplating raising the front sight- somehow. I appreciate seeing the two barrels side by side ;2" vs 4" and see the sight height difference . it is not what I tought it would be as the 2" sight does look taller. But my calculations for my snub is it needs to go up about 3/16" . Anyway how did the barrel come off ? easy or hard and look like it is just pinned in so what keeps it from wobbling ect ?

I do recall it hitting high with the 2” barrel with some ammo, but I do not recall which ammo.
To be honest I did not shoot the gun much. My dad liked it. Trouble is I didn’t like my dad much so whenever I handled it I thought of him, but all that is not a story for here.
My sister expressed interest in it so I installed the 4” barrel.
Removal of the 2” barrel wasn’t too hard. I removed the pin and secured the barrel in a vise sandwiched between 2 pieces of soft pine.
It took a little bit of torque to break it free, but once the initial “crack” occurred it actually took a bit of effort to twist the barrel out of the frame. It had a tight interference fit.
There was a hard white substance in the groove between the machined surfaces. It looked like hardened white lithium grease.
When installed the 4” barrel I used the Loctite for cylindrical surfaces. The liquid helped lubricate the installation, but it was definitely snug. It took a little work and a little cussing to get the barreled lined up with the pin holes. I kept going just a little past the alignment holes in each direction several times until I got it aligned. The pin is also interference fit.
All in all it really didn’t take long at all.
I shot it at the range using some Winchester ammo I had to test it out before shipping it to my sister.
It hit close to point of aim at 10 yards.
She has had it for a few years now and only fired it a couple of times due to the cases sticking.
I have it now to polish the chambers for her.
She asked me if I would like it back, but that’s a big “No” for me. I will get it polished up and she can have it back.
