Had a few over the years, I had a Beretta 84 I bought used, as are most of the guns I buy, and the rear sight just flew off and hit my shoulder and dissapeared. We looked and looked for it, and couldn't find it. Finally, I gave up, and I was going to order one from Beretta. A couple hours after I got home, the range calls and said they found it in a bucket full of 9mm brass that had been sitting a LONG way from where I was shooting. I had the smith there put it back on, and it never came off again.
I had a really horrible little gun, an FTL Auto-Nine. If you didn't use .22 "standard Velocity" ammo in it, off went the extractor. Sent it back, found the right ammo, and off it went again. They told me I had to use XXXX ONLY ammo, or my warranty would be voided. I sold it on consignment, with the note from FTL in the box, with a 50 rd box of the stuff they said to use, and the dope who bought it put stingers in it anyway, and blew off another extractor. Not my problem at this point, I was glad to say goodbye to the thing, it was totally unreliable anyway.
I had an S&W 59 that looked and shot great, but suddenly, the safety came apart while shooting, and the control part bounced accross the range, it had sheared off, and when looked at closely, was obviously badly cast in the first place. S&W sent me a new one, and also gave me a mag tossed into the box.
Oh, I forgot, on one of my DW model 15-2's, the cylinder stop came out and I went and dimpled it slightly, and used the loctite stud lock and a press to put it back in. It never came out again.
