OK so after 20 months with my SR9 I finally had a serious issue today. Whilst blowing up a frozen Pumkin that was on my porch since 10/31, I had an excessive series of FTF's today. Guns are cleaned before and after every shoot, and complete takedowns at least once per month. With only a few rds. At a time loaded in Mag., it would jam on the 2nd or 3rd rd. Cleared the chamber and switched mags( I have 5 for the SR and 7 now for the LC) loaded 1 into mag and then chamber for wife to try. Three times in a row gun failed to fire, took it from her, figuring she was having issue with the trigger, tried it myself, still no BANG,. Brought it home and broke it down again, found nothing obstructing mag well or chamber/Feed Ramp area.... Any thoughts?
