Posted this on another forum, but want to get more comment:
O.K., these observations are primarily directed at those who've put around 500+ rounds thru at least one of the sr22 magazines.
Background info is that I've had the pistol for some 4 years and have shot maybe one to two thousand rounds. Exclusively used cci mini mags. After about a thousand rounds I started to have failures to return to battery in one mag. Ruger sent me a new one and I've used it for about 500 rounds without issue. However, just recently, my other mag had two issues, one fail to return to battery and one instance of the slide not picking up the next round ( weak round is always a possibility).
So, upon inspection, I noticed two "issues":
1. I had never disassembled the mags for cleaning although I wipe then down after every outing. Upon doing this, I was surprised to see a moderate amount of debris/residue, maybe enough to cause a problem? Can anyone comment on their observations/ cleaning routines?
2. Next, I observed on the two mags that had issues, an anomaly wrt the feed lips. The right side, rear feed lip had a small "divot" at its rearmost point. Neither the replacement mag nor my spare mags show this. Has anyone else noticed this?
