I don't mean to sound argumentative, or like I'm trying to tell you what to do, but please do some research. The J22 is not a proper defensive weapon. If you want to stay with a pocket pistol, there are plenty of good, inexpensive guns. You don't have to spend an arm and a leg for a midsize gun, either. I own a S&W Sigma, and it ran me $300 brand new. Not all $400 1911's are garbage, either. RIA's, and other Fillipino 1911's are great bargains.
There are options, you just need to do some searching, shopping, and most importantly, researching.
