all i can say is when i shoot my open gun (2011), along with everyone else shooting their 2011 limited or open guns, it's an obsession to keep the mags clean, prescreen all the ammo and expect the occasional jam, religiously clean the gun after each match..
when shooting glock, all the focus is on shooting, not on clean or dirty mags, what ammo you're feeding it, malfunction drills, etc. and if it goes a few matches without getting cleaned, so what.
but clearly glocks don't come close to 2011 triggers.
