I don't normally take sucha hodge-podge to the range but these are all guns I haven't shot yet and I wanted to try them out.
The M9A3 is a pleasure to shoot but I would like to change the sights. I will probably send this one off eventually for a trigger job, sights, and to have a second barrel cut flush with the slide. As it comes it's absolutely a great handgun and the trigger is pretty nice. But being a pizzagun fanboi and all I think I'll splurge on this one.
The USP will let you know you're not gripping it hard enough by just plain being uncomfortable to shoot. At first I didn't like it but I often find myself not gripping handguns hard enough so this will probably be good for me in the long run. Plus it's too cool for me to get rid of.
I almost forgot to grab mags for the Glocks so I just grabbed the first mag I found, a 21 round Pmag. It wasn't broken in yet so it failed a bunch and I gave up on it. All my other GL9 mags took a lot of cycles to break in and start working so I'll find something to push on the follower and cycle it a bunch and see if that helps.
