I have a Glock 22 Gen 4 with very low round count . It comes with 4 factory back straps and 15 round magazine and the factory box and all it's contents it came with. I have 2 more factory magazines that will go with the gun ( IF ) I can find them. The gun is in immaculate condition. I clean and oil all my guns after they have been fired and it has always been stored in a climate controlled gun safe.
