CCI Stingers aren't new...I seem to remember them from two (2) ex-wives ago
I remember when they came out in the late sixties IIRC. Everything had to be FAST back then, never mind the 33 grain bullet.
I guess there was a general "Super Vel" mania going on at the time. Remember "Super Vel?" .357 magnum, baby! 125 grain bullet at 10,000 feet per second, or something close.
A .22 is just a .22 and out of a pistol it ain't even THAT. However, it's still a very useful tool to the outdoorsman, make no mistake, that's why I have so danged many of 'em. I even carry one as a back up just because it's so small and light, why not? It backs up a .38 or a 9x19 usually in my strong side pocket. It's a 5 ounce (+ probably an ounce for the folding grip) NAA mini revolver. It beats my teeth. It'd hurt pretty bad if I screwed it into the BG's ear, way I figure. Hopefully, it'd penetrate his ear drum, give him a headache.
Seriously, a .22LR out of a handgun is NOT a toy. It can kill you. It's just that you're trying to stop a fight NOW, not in a few hours or even a few minutes. I do, on occasion, carry a NAA Black Widow .22 magnum when I need ultimate concealment. It makes right at 100 ft lbs with a Hornady Personal Defense 40 grain JHP. This is pretty close to the 120 or so ft lbs of a .32ACP, but the .380 is over 100 ft lbs up on it. It's quite accurate, though, and that becomes more and more important with smaller calibers. It WILL expand on a center mass shot, something most .22LRs won't do at short barrel handgun velocities.
Anyway, the .380, even the .32, is MUCH preferable to a .22 or .25. the .22 mag doesn't give me thrills either, but then I'd rather carry my 9 than my .380. You carry the biggest caliber you can at the time, make sure you can place the bullet where you need to. I have choices. 99 percent of the time, I can carry a snubby .38 or 9mm subcompact as a pocket gun, not a problem. I have a .380 and a .22 mag for times I can't, but fortunately they don't need to be fallen back on very often.
