Yeah Dumpy, or sorry, Lumpy grits.
I'll agree, that, yes parts do break, and acts of god etc..., shit happens, then you deal with it. But, to show up at the range and have a rifle or pistol not perform as designed by the manufacture because of a fouling of the action or trigger assembly, then yes that is your fault and nobody else, and no one can be blamed for your oversight, weather it was intentionally or unintentionally done, but you, period. When I trained individuals in hostage rescue, S.S.D.F., and as a D.O.E. Tactics and Small Arms instructor, rolling through the mud, sand, water, and thick and humid jungle's of Central America, I can honestly say that, I've seen just about any and everything that could happen and that has happened, to small arms, both as a operator, and a investigating official.
And, Yes after years of training ten's of thousands of Army, Navy, Marines, and Coast Guard, and civilian's on the use and employment of both deadly force and small arms. As a Small Arms Expert, I've trained and used everything the military uses, from 22lr through to .50 caliber rifles. I know that for a fact, that I've most likely trained and have shoot more, than most people. Its what I did for a 30 year career, and still do to this day compete in long distance (1000yards) and every distance in between, and yes, I'm pushing 60 yrs old myself (of course, your only as old as you think you are), so, yes you could say that I probably know what I'm talking about when it comes to Small Arms, and their use. So when you want to sit down and compare experiences, then give me a call.
