It's all in the training.
I've competed with one 1911 or another for 20 years, and the safety flick on draw and line-up is muscle memory. Done it a jillion times, live and dry.
Competition stress is the next best thing to the "real thing" and I have no doubt that when my mind says "draw" I'll be able to put a round on target without thinking about the safety. It'll just happen.
Glocks, on the other hand, scare the hell out of me.

Different strokes.
I second that. A friend of mine was field testing one. Wasn't sure of the sight so he decided to "walk" a couple of rounds in. First round hit about 10 feet out. Scared the Bejesus out of both of us.
The next month one of the big time magazine writers described a similar event when he was testing one.
