I've been ONLY using my G35 at all the GSSF matches, because that's MY competition gun. Now that I've accumulated a couple more Glocks: G17, G27 and G23... What match categories can I apply for the next match? On the GSSF registration form: I see... Amateur Civilian, using 17 Amateur Subcompact, using 27 Amateur Competition, using 35 Master Stock, using 23. Is that correct? Do you guys use multiple Glocks at GSSF? Which categories do you guys participate in? Thanks for reading.
