HELP! I posted this on the Rimfire Handguns forum, and thought I would copy it here as well. I've got a new Beretta 21A in 22LR, and in the last month since I've purchased it, it fails to feed, stovepipes, etc. It's rare that a mag will run all the way through. I've tried using WW Power Points, Rem Yellow Jackets, Blazers, Rem HS HP's etc. All seem to have their problems in cycling the action. CCI's Stingers have functioned perfectly, however, leading me to believe the extra power is compensating for some manufacturing glitch. Oftentimes the slide will push back, but either not eject the fired case, or the fired case will eject but the next round won't feed. Sometimes, especially with the WW Power Points, the case will eject but the next cartridge won't feed, preferring to ride up on the feed ramp and jam between the slide. I've stripped this down to the pins, smoothed everything up, clean it religiously after firing, even tried different mags (Beretta and a Mec-Gar). I'm not seeing much improvement. I've already put over 500 frustrating rounds through her. Has anyone else had similar problems with this little Beretta, and what have they done to solve the feeding problems? My next step is to send it back to Beretta under the warranty, but I hate to be without it for too long.
