Given that, I don't tend to recommend it for the beginner. A Glock is designed to shoot when the trigger is pulled, every time, so it's a minimialist pistol i.e. no manual or grip safeties. A Glock owner has to remember always the primary weapon safety is between the ears.
If you choose the Glock, splurge for a weapons safety course and a good holster (covers the trigger without risking engaging the trigger bar). In the end, it's your money and your life so choose what feels right to you. And have fun!
I'll have to see about that part. I guess one's reaction is as unique as one's hand. I'm just going to have to see for myself. MikeJ seems to have a good test that I'm going to try.
