*Please Note:  Glock does not sell only the slide for Gen3 handguns.  They only sell them as full guns to FFL's.  Since they are sold as full guns, then the slide is taken off and sold again, the Factory warranty is void and all warranty issues should be handled directly with us, or whoever you bought the slide from.  To date, we have not had any issues that come to mind, it is usually the finishing of the P80 frame that causes any problems.
