I just jumped into the world O Glock with a recent G17 Gen 4 purchase I haven't even picked it up yet the dealer had to order it for me , the matches look interesting , not to difficult but a good place to start with matches outside of my own clubs matches , the price of entry isn't to bad , well once you already own a Glock pistol.
I don't see anything prohibiting 2 people from sharing a pistol in what I have read but I was thinking my son would probably like to shoot a GSSF match also and needing a Glock to play and only having one at this time sharing would be necessary.
the match I am looking at is Oct 3-4 west of Milwaukee about an 90 minute drive for us so not to bad.
