After reading many posts regarding, what modifcations are legal, for a Glock, used in a GSSF match. I have a question. The only match I have shot in so far, was Nashua, in July. But it just dawned on me, that, nobody ever asked to see my pistol, I made sure my pistol was legal, before going, but how do they know that. I don't recall anybody looking at anyone's Glock, except for people dealing with the armorer. Back when I was racing, they used to tear us down, when we finished in the top three. Is it the same type of thing with GSSF.
