I second the Walther P22. I purchased one new, probably not long after introduction. S&W worked on it and corrected most, maybe all of the feeding problems, but the pistol remained inaccurate. In fairness, however, I'll mention that I've read reports on later guns - seems they were considerably better than mine.

I've had several stinkers, but no real disasters.

First was an AMT Backup 380. I bought it new and had lots of FTFs. Sent it back and they installed a new, stronger, hammer spring in it. It was uncomfortable to fire; it was light and came back fast. The grip safety took up most of the back of the grip, so the recoil was transmitted to my hand through the two strips of tghe frame on either side of the grip safety; about 1/16 inch wide. It didn't feed or eject too reliably either. So as I didn't like practicing with it, and distrusted it as a carry gun, I sold it to some guy who worked as a rent-a-cop atg a local dance hall.

Next was a Browning Baby 25. I couldn't fire a magazine full without an FTF. I tried different magazines and different brands of ammo as well as my cast bullet handloads. I looked at a Bauer 25, a copy of he Browning. It had a little scallop on the top of the breech face. I had a gunsmith put one on the Browning; it helped a little but the thing was not reliable. I've heard many stories of problems with these guns, including a return of about 100 of them bought by some police force in NJ as backup guns.

Last was anything made by Colt, resembling a 1911 but chambered in 22. I sarted out with a conversion unit: it would only fit my Rem Rand WW II pistol; no other 1911 or my Series 70. On the Rem Rand the floating chamber clogged from powder fouling after a couple of magazines. It was a pretty thing, in its littlle brown box with green insides and it sold quickly. The next one, somewhat later in manufacture, wouldn't fire reliably although most went off on the second whack. After a little firing without cleaning, it wouldn't eject, either. Had a lot of trouble selling that one. Finally went for an almost new, very pretty (and very expensive) Colt Service Model Ace. It wouldn't eject after about two magazines. I'll try one of the new Colts made by Walther and see if they work any better.
