magazine causing feeding issues?

[LRRPF52]

The 17rd CProducts mags have been the biggest culprit in feed issues. The 10rd and 25rd mags have very few complaints from what I've noticed. I have a 17rd mag that I have used since the beginning with only 3 and 5-round groups, thinking it was 100% reliable, until I loaded it with 10rds. Then it choked. I should just block it off, and check the other one for 5+ rounds reliably.
