I've got a G17 and a G26 that I plan to shoot in Civ and Sub this weekend at Conyers. I also have a friend who wants to give GSSF a try. Only problem is that he is currently Glock-less. Is there anyway we can share the two guns and both of us shoot 2 classes? I have 8 17rd mags and 2 10rd mags. Thanks! PS I did try a search, but came up empty handed. Sorry if this has already been answered.
