My wife has a 22c for about 3 years now. In that time she has put several thousand rounds down range. We have found that it is somewhat picky about what kind of ammo it likes. Standard velocity can be problematic so we only use only high velocity ammo now. It works flawlessly with any high velocity we've tried except Federal Automatch. We usually stick with 40gr Mini Mags, but Aguila, Fiocchi, Sellier and Belloit, and even Remington Golden Bullets cycle without issue.

We clean and lube it ( generously ) after each range visit.
