.22 magnum for personal defense

It would be interesting to know the cylinder diameter of the High Standard vs. a true J-Frame cylinder diameter.

It's fairly easy to stuff 9 into something like a Ruger Single Nine which is a gun with no extractor star. But in a swing out cylinder double action gun, there has to be enough meat (strength) on the extractor star to punch out all the spent cartridges at once. I'm sure we've all experienced rimfires that don't eject as easily as centerfires.
I had a Sentinel Mark IV. It was the same size cylinder as my snubs. Much smaller than my Speed Six. Neat firearm, but the trigger was the most horrendous that I ever felt in a rimfire revolver. Only reason I sold it.
 
John Pride, LAPD, reported doing the same during the Watts Riots. A .38 and 18 rounds was not a confidence builder.

Ya know. I remember something like that. That’s probably where I got the idea.

He said something about if he were trapped in a tenement as the crowd outside was trying to get to him, he could hold them off long enough for help to get there.

That sound familiar? Man. That was a long time ago.
 
I don't like carrying small insufficient caliber handguns for self defense.
22s and 22 magnums are small game guns.

I have a K-frame snub, its cylinder has lots of room compared to a J-frame cylinder. I wonder if the Mark IV cylinder is closer to a K-frame cylinder?

The J-Frame cylinder in .22 WMR looks pretty snug getting 7-rounds into it as the image in the links below show.

Say no more!

Measured with old-school vernier calipers, so I could be two thousandths off or so. All measurements in inches.

JC Higgins 88 (which is a High Standard Sentinel by another name, although this is a 9-shot .22 LR and not the latest model of Sentinels) is 1.369

Have no fear, I’ve got a Diamondback Sidekick, which appears to be a High Standard clone with a 9-shot convertible cylinder! 1.371

Aah! I don’t have a j-frame!

How about an LCR in .327? 1.283

These are diameters, circumference may be the more easily discernibly important dimension.
 
Can't beat science. But the differences are pretty miniscule. The High Standard is definitely not large. No reason why it can't be done today with the current modern manufacturing processes.

Thanks for those. I measured some cylinder diameters for comparison. Rounded off to the nearest hundreth, give or take.

My only current "J-frame" guns are Charter Arms, and they are known for making their .22 LR Pathfinder with 8-shots now.
C.A. Pocket Target (aka Pathfinder) .22 LR = 1.30"
C.A. Undercoverette .32 Mag = 1.30"

Not a J-Frame, but the cylinder sure is small enough to be in range of a J-Frame.
H&R 999 .22 LR 9-shot = 1.34"

So, if the H&R was made into a .22 WMR (with a longer cylinder) then it would be reasonable to assume that it could hold 8-shots of .22 WMR. Proving @KevininPa 's point.

For further consideration, the Ruger Single Six cylinder is 1.42" (which is right near K-frame size of 1.45"). And the Ruger Bearcat cylinder is 1.22". But neither of these guns have an extractor star in the cylinder.
 
i tried a ruger lcr and a naa black widow chambered in 22wmr for a ccw. even handgun specific 22wmr ammo seems to offer little better practical effect than 22lr cci stingers from a short barrel, but with alot more distracting flashbang at 50% more cost. a ruger lcr or naa bugout1 chambered in 22lr is way better for me, while 22wmr is reserved for a 5.5” ruger single six or a rifle.

I am not a fan of Ruger DA .22 Mag revolvers, but they only make it in the LCR and choosing it over LR means losing 2 rounds. Ruger could have made it a 7 shot, but took the easy way out given they had plans to do the .327 in a 6 shot LCR.

After S&W, the only other quality alternative that isn't a half hearted effort is Taurus 942, those are an 8 shot in either LR or Mag and cost $200+ less than the LCR.

i had a taurus 94 22lr. earlier model, not 22wmr; yet trigger pull was absolutely 200% atrocious, and totally unlike taurus’ fine centerfire revolver triggers.

i swapped my lcr 22lr’s orginal boot grips for ruger’s extended grips, which changes the lcr’s design geometry entirely for the better. i wonder if the lcr 22wmr would be better with longer grips, found on the lcr-x’s longer 3” barrel, or a new 4” barrel model?
 
BTW, I had years ago a 6 shot SW 651 3 inch 22 Mag. Very pretty and nicely made gun. The problem was that in those days, 50 rounds of 22 mag ammo would glue up the cylinder and works rock solid with the remnants of the blast. It took a can of crap-be-gone to free it up and then taking it apart to clean. If today's short barrel revolver 22 Mag is different I don't know. Sold it as it had little utility for me then.
