The glock would do alright. 40 is really the smallest caliber I'd use. as far as the pins go, if you get a straight on shot to the thick part of the pin in the middle, the bullets usually get stuck, unless you're using Rumbler hot 10mm loads. anything to the sides usually penetrate through. problem is, throughout the match, as the pins get shot, they get heavy and deformed, and that's where 9mm starts to really suffer.

the match is done from 25 feet away, with the pins on the front edge of a 4x4 table, pins have to be knocked off the table. Match is a heads up drag race, first of the 2 people to clear their table wins. 6 rounds in your magazines, have as many as you want, match starts loaded at the low ready.
