I plan on going to a GSSF event next month for the first time. The main reason is to get all my followers replaced in my G19 and some minor upgrades to my G19 and G22. I think it's a deal for $25 to have your guns upgraded and to learn some things. Next question is I have never shot in a match before and I want to know if they have first shooters events? Also how much ammo to bring and do I sign up there at the event or do I have to do it online? Can you guys help out a first timer with the info and what to expect. Thanks.
