I'm not going to say the Glock is for everyone (it's not). But I do believe it has certain inherent qualities that make it faster at speed than many other designs. Quite frankly, when I'm doing it correctly I know specifically because it's not comfortable or natural. There's pressure on certain joints that keep things locked in place for faster shot to shot recovery.
I can run .15-.17 second splits with good hits at 7 yards with a Glock. I can get those times with a Sig, but not with good hits. The gun is just squirming around too much. It's a matter of physics, not psychology.
You mention competition and I understand your point. But I consider personal defense to be the ultimate competition. It only takes a millisecond to break a shot. If I can get good multiple hits on target a few hundredths of a second quicker, it might get me less shot. That's the most important thing in a gunfight.
