I am new to GSSF and was going to shoot my G17 and G34 there. Three questions (in bold): My G34 is bone stock and I would shoot this in the Competition (Amatuer since I do not meet Master reqs) classification (am I right on this?). My G17 has the following mods: 1) Glock factory extended mag release. 2) Glock factory extended slide stop. 3) Glock factory 4.5 lbs connector (i.e., the same connector as on the G34). Would my G17 be legal for the stock civilian division? Can I shoot on Saturday with my G17 and G34 and then return on Sunday to shoot with a G37 (again in stock civilian)? Thanks for you help. Nem.
