I've been going through the same decision process as the originator because I want a pocket gun. Got some good advice on a similar thread.
My question to you is, why trust your life to a POS gun?
A comment to everyone else. This confiscation business has to be stopped. It makes no real sense. If I acknowledge I shot the perp (hey, he's there, dead, I'm standing with the gun), what's the point? The police don't have to prove it's my round in anything but some extreme circumstances. Of course they will run the S/N. So? And, if they want further testing, well, they'd have me come in another time (than the event). If they can't do that, then they'd arrest me on the spot, in which case there's no point to the CCW permit system at all, is there. Then there's the civil trial. Let's see, it can be brought in, and verified from the original police report, can't it? If they think it won't, then what makes them think I'd show up?
So, in a legitimate shooting, there is no reason to confiscate and store a gun for a period of years. It is merely harassment, or an attempt to block ownership, or could even sink to an attempt by some of the cops to add to their own collections. (If after 3 years in "evidence" the gun can't be found, do you seriously believe they would do anything other than shrug? And, if you pressed the issue, the usual cop response, "You want trouble?")
This aspect of the law needs to be changed by adding it to the CCW provisions.
I had intended to quote an earlier poster who said he wanted a POS gun.
