I agree, call first then send it back. One note: as you disassemble the gun, the recoil spring may slip off that lip on the barrel extension...though I doubt it's possible to reassemble the gun without it being firmly seated there. Glock should make good on this for you. Have you called them as yet? Rod
Cherish our flag, honor it, defend what it stands for or get the hell out. Our Freedoms are not free, they've been paid for many times over by heros in uniform. Far better men than I, died that we could be FREE.
