The P22 is a quite robust, VERY reliable, lightweight .22LR pistol that is not only a good plinker, but an even BETTER "carry gun"!
It may be fairly reliable with specific cartridges, but generally speaking .22 LR autos are finicky, and carry weapons obviously should be dependable.
Forget all those who've never been an a firefight, or never seen what damage and lethality a .22LR has, or all the BS about unreliability versus centerfire.
The fact is that most .22 LR ammo is made with low price as the first priority, and that's OK as long as we're aware of this. A couple of misfires every few hundred rounds is common, and may be as high as several per hundred in the worst brands (e.g. Remington where rimfire is concerned). That's according to my experience and those of many here. There is reliable .22 LR ammo, but you have to know what to buy. Your blanket statement calling the whole issue BS is not helpful.
As for lethality, yes .22 LR can be quite lethal even when shot out of handguns, but it is critical to choose the right ammo--more so than it is for larger calibers.
Ballistic gelatin tests prove that high speed .22LR "solids" will punch every bit as deep as any .45...or 9mm.
Not every cartridge in every handgun, and not when compared to solid 9mm or .45 ACP rounds. .22 LR can achieve what is generally considered adequate penetration when you use the right handgun-ammo combination, but you need to know what you're doing.
The fact is the .22 is cheap and easy to shoot.
Those are indeed great advantages, and precisely why I've recommended it to beginners for personal defense, but advice on specific weapons and ammunition, as I've given earlier in this thread, is extremely important in this caliber.
What the .22 is NOT suited for is shooting through walls, car doors, or other barricade material.
Correct, although it should be noted that while less than ideal for this task, .22 LR out of a handgun may be able to penetrate one or even two interior walls with enough momentum left over to potentially kill.
I hope you ended up getting the Walther for your girlfriend and I hope you discovered what a GREAT little carry gun it is!
For defensive purposes with .22 LR, get a revolver--please, seriously.
What I was trying to find out was , how good a pistol the P22 is .
It's pretty nifty in its own ways and fine for the range, but it's not one of the better .22 LR autos, and I wouldn't depend on any .22 LR auto for defensive purposes anyway.
She wont go for a revolver , she wants an auto . Any other ideas would be great .
Did she give a reason? My mom didn't want a revolver either (for home defense) because she considered them clunky and old-fashioned, but she changed her mind after I had her try a S&W 617 at the range. It's big and heavy, but with it she can pump out round after round with deadly accuracy.
The jams she got with .22 LR autos undoubtedly played a part, but she's no longer biased against revolvers in any event.
The only way that even your girlfriend herself will know what she likes for sure is to try out different guns at the range. If she still wants a .22 LR auto regardless of the advice given here, then I guess it's better than nothing. In that case, the Beretta 71 (brought to our attention by geologist) sure looks intriguing, although I can't vouch for it personally.
