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
Our Flag does not fly because the wind blows against it,
It proudly waves because a soldier's dying breath blows upon it.
