I've really enjoyed my P22. I shoot mini-mags or the CCI "AR tactical" boxes and have had no malfunctions I can recall in ~1000 rounds. Last time I cleaned it, I did notice peening on the "bump" on the frame rail. Easy to break down and clean.
All that said, I would like an SR22 and will probably get one some day.
Shoot smart. Shoot S-Mart.
