Well, an RG was a true POS, but give me a break, I was a kid.
Had a Phoenix Arms HP22 crack a slide early on, couple of cartons of ammo into it. To Phoenix Arms' credit, they made it right. And, after all, it's a cheap little pot metal .22, but it shoots very well. They redesigned the slide, so I guess there was a design flaw with the first ones. They sent me a new slide and spare mag to go with it.
I busted a firing pin on a Rossi M971. Sent it off, came back., broke on the first range session. I had a smith fix it right. This was in Rossi's Interarms days.
Had a Smith and Wesson M10 of unknown, but fairly light round count split a forcing cone for unknown reasons. It had little if any wear, mostly shot wadcutters in the gun and that's what I was shooting when it split!:banghead: I bought a heavy barrel off an outfit advertising in Shotgun News and had a smith install it. I like it better now, actually, balances better and shoots just as straight as the old pencil barrel.
I had a Beretta Minx .22 short that never did work. Got rid of it at a gun show. Junk.
I've owned a lot of handguns and those are the only ones I can think of that have broken. Three of 'em are Taurus revolvers and one's a Kel Tec P11, much maligned on this and other boards, but have all been perfect through many thousands of rounds each. Two out of five of the ones I had problems with are considered "brand names" and "high quality". Go figure. I have to agree that the M10 is otherwise high quality, but I don't have much of a good opinion of the K frame's forcing cones. And, guess what, I had a RG26, little POS striker fired .25 auto I carried for years when carry was illegal. It wasn't very accurate, but it never malfunctioned. ROFL!
