What does it matter? You made an empirical statement that "If you take A class with A 1911 it WILL fail". He proved your statement wrong with his personal experience, now move on.
Or, you could just go take another sip of your fruit-flavored, powder-based beverage.
Oh,did someone ruffle your feathers so much that you went from gun debate to personal attacks? I can and love to play that game but not here sorry.
There's a reason for specific questions.
My all didn't mean 100%, I was generalizing.
Type of class matters because of what stress is being put on the gun.
The fact of the matter is that 1911's are inferior to glocks. Get over it
