There is nothing wrong with the Beretta. I would have bought one when I started law enforcement, but I wanted a .45. So Glock it was, back in '95 there wasn't many options in a good semi.

Believe or not, one of the instructors frowned on 1911's, because they where single actions with lighter triggers. Now before y'all get pizzy about that remember there were lots of females and non shooters in the bunch.
They also claimed the 1911 wasn't as reliable with some hollow points in their opinion.

The only other auto I had experience with was a 459 S&W. I didn't like it much. Creepy trigger, just the general feel of it.

Colt had the Double Eagle, but they were hard to find and more expensive. Same with Browning autos and again a 9 mm.

So I started with Glocks and stayed with them.
