GSSF is out for me because I don't own a Glock. I downloaded the GSSF rules, and saw that they just added a class for the Glock 42, which means that even my daughter could compete with her tiny little .380. I must admit that I am becoming increasingly interested in Glock as I've studied their 2016 product line up. My EDC is a Kel Tec P11, and my primary home defense handgun is a SIG 2022 (both are 9mm), so there'd be a class to compete in for either of those pistols in USPSA.

Jafar, you can Youtube either event and get a pretty good perspective of how they go down in different venues. At one point, there was even a ariel drone-shot video of a USPSA event at Talon on Youtube. I attended a USPSA event at Tallahassee Rifle & Pistol Club before Talon became the venue, and I thought it looked like a fun event.
