I posted this on general forum. No reply. Maybe someone in glock forum can answer. I have glock mod 22 when I try to reassemble after field stripping it slide stop just short of when it should cock weapon. This is new glock and I must wiggle slide side to side and sometimes in a twisting motion to get it to go all the way back and cock. Is this due to weapon being new and just needs to break in and loosen up or is this a real prob? I`ve owned 1911s and other pistols but this is my first glock.
