Hi to all. I went shooting over the weekend and noticed that after disassembling my 27 after my range session, I noticed that there was a wear mark on the inside of the frame just above the trigger guard. As I inspected the Recoil Guide and Spring, I noticed that the Guide was slightly bent into a concave shape. I believe that the bent guide was rubbing on the inside of the frame causing the wear mark. Don't know if the guide was defective or what? My question is, did anyone ever hear of this happening? Should I just purchase a new recoil spring and guide, or send the gun back to Glock? Your advise would be greatly appreciated. Thanks.
