There was about a 5 year period where almost ALL the semiautos I bought were duds. New, used, it didn't matter! One after another, FTFs, stovepipes, etc. It was like I was jinxed. Revolvers were another story completely, I had a bunch and they were all great. I had a lot of free cash to buy guns and the bad streak never seemed to end, .45, 9mm, .22, POS after POS. Three good ones came out of that period, all made by Beretta. The first was a 950 I bought as a backup gun, after many .22LR disasters that included the FTL Auto Nine, several PPK clones, and more than a few others. The other winners were a Beretta 84, and a Browning BDA 380. Pretty much perfect. The other duds ranged from an almost OK PPK, to a Browning HP that was a better club than a gun, a Colt Combat Commander that was pretty useless, an AMT Hardballer that never saw a round it liked, an AMT back up 380 with a trigger pull that exceeded most people's ability to pull it, to LLama and Star 1911ish turds that limpwristed constantly.
Weird thing is, it all changed when I started buying lots of guns again in 2006, I haven't had one bad one. Not one. Most have been in better condition than I had thought from the pics on the auction sites I have bought most of them from. Revolvers, semis, new, used, it doesn't matter, I've had great gun after gun, and I keep wondering when the winning streak will finally end.
