1. I'll admit that I prefer the grip angle of the 1911.. and most of the shooters I know do too.
But there must be a reason why the Glock's grip is the way it is. Anyone know?

- I read the Glock grip angle is the same angle your hand naturally makes when you extend your arm and point your index finger.

2. I think I know the answer to this one, but why is there an indentation on the broad side of the grip? Is it a thumb rest for one-hand shooting?

- Correct

3. Why is there a finger grip on the forward section of the trigger guard? I shoot both thumbs forward, support index finger under the guard.
Are there shooters that index on the forward guard to control muzzle flip? (if that's what it's for).

- Not all countries teach the same grip. The index finger of the left hand is pladed on the fwd side of the trigger guard.

This was from some info I read on Austrian Marksmanship.
