Oh ok. I never thought of that.. I was thinking about saving my 9mm brass and then reloading it for a 9mm major (open) gun. I guess that could get me into a snafu if i mixed them up. I haven't read too much on the glock barrels but if i throw a KKM in, i should be good to shoot major out if it? That seemed to be one that i read others using for major...
Thanks guys.
