I can sure tell you this, I have watched about a zillion guys at the range with Glocks and rarely, and I mean rarely do they have any malfunction of any kind. They just run, day in day out, don’t care what you feed em, clean or dirty, they just run.
I shoot my M&P much much more than my Glock but I can honestly say I don’t remember ever having a malfunction with it either. My 1911 was a Ruger SR1911, it’s been years since I sold that gun so I can’t recall it’s reliability.
