I am specifically referring to the types of torture tests people post about online where they cram the guns full of sand/mud/twinkies/whatever and see if they still shoot. I have seen threads on various forums dealing with these tests, and have seen known reliable guns like HKs, M&Ps, Glocks, and Beretta 92s all fail.
At what point does a torture test go from realistic/useful to ridiculous/expecting-too-much-from-a-handgun? How do we determine this? Is cramming a semi-auto with foreign matter a realistic test? If not, how much foreign matter is reasonable?
