I recently bought a Glock 23 and every time I field strip the gun for cleaning I find the recoil rod has come partially out of the "half moon" cutout at the base of the barrel. I can seat the recoil rod firmly, reassemble the gun, then cock and dry fire the gun and strip it back down only to find the recoil rod has moved from the original position. It never comes totally out, but it does appear slightly bent and the full force of the recoil rod is on a surface much smaller than the full "half mood" cutout. Is this normal? If not, any ideas on why this may be happening? Thanks in advance for your replies. fyi - I've attached a .jpg file showing the recoil rod after one dry fire cycle.
