If it doesn't start with a "4" and ends with a "5" than it's not getting carried.
I trust my life with ultimate stopping power.
All other calibers are inferior.
Lol, nice impression of...
Oh wait, never mind
I carried a 22lr LCR for a while. I'm carrying same in 38 at the moment. There is/was logic to the choice:
-originally carried a G19 for a few years and was muscular enough to conceal it in T shirts
-took some Shivworks classes, size and strength weren't relevant if I gassed out, so I started doing more cardio... Also had to cut back on bodybuilding hobby due to busy self employment lifestyle
-summer rolled around and suddenly the g19 wouldn't conceal, sure I could have gotten a single stack 9mm but for various reasons a revolver was a better choice (round butt conceals better for me than a squarish one)
-didn't own any 38, ammo shortage was at its worst, did own a few thousand 22lr
-purchased 22lr LCR and got some training to get proficient with the gun and be able to actually conceal something, anything, in summer
-once 38 became more readily available for purchase I got the same gun in 38 and the 22lr version makes a great teaching gun and one I can recommend to people who don't have as much to spend on practice ammo or who are recoil averse.
I will keep it brief but my view on 22lr is:
-judging by most people's targets at the range they'd be well served by a more shootable caliber since they aren't getting good hits
-comparing good hits with a 22 to good hits with a larger defensive caliber I believe the speed of hits with the 22 in many cases makes up for the smaller wound channel. Penetration isn't great but it isn't that bad either.
-performance with intermediate barriers is probably very poor which is one of the main reasons I chose to stop carrying it.
-whenever I hear 22lr being bashed as a defensive caliber in a broad brush stroke way I don't necessarily think it is being under rated but I do think those people over rate the bigger pistol calibers quite a bit
