I've got a Phoenix Arms HP22 I like a lot! Yeah, it's zinc, it was cheap. And, no, I don't carry it for defense. I've shot rabbits with it, though, and snakes. I made a little pocket holster for it, great for bummin' around when you want a concealed .22 for that sort of thing. I even bought a 5" barrel for it and finger extension magazine. The thing has had a few problems, but Phoenix Arms is really good with customer service, fixed me right up and quick. I've put a lot of rounds through that thing plinkin' at cans and such. I occasionally have to put a recoil spring in it, but they're so friggin' cheap, it's not that big a deal.
Oh, I've got better guns, but this is the only pocket .22 I've had that can shoot 3" at 25 yards with CCI stinger, pretty cool and pretty useful as an outdoor pocket tool. I can tell ya this, I had a Beretta tip up .22 that was a jammamatic and experienced light hit misfires about every third round. The HP22 works MUCH better even if it ain't steel. That Beretta was junk. It was cheap, too, just not quite as cheap as the HP22. I mean for the 70 bucks I gave for that thing, I don't think I went wrong on it.
The Davis P380 I had shoot 4"-5" accurate at 25 yards, was quite reliable, and never broke on me. I did, however, get a better gun for carry and sold it. I don't like striker fired guns for carry, good shooter or not, zinc or steel. But, that Davis did work pretty well. I'd shoot it and if you have emotional attachments to it, I'd definitely keep it. I have a couple of my grandpa's guns, a M10 Smith and a Remington M722 in .257 Roberts. I ain't sellin' either one. Of course, they're good quality guns, but that doesn't really matter. I wouldn't sell 'em if they didn't work just for sentiment.
