Upgrade your Glock 19 with a competition ready slide from Primary Machine. This Slide is machined from stainless steel and is milled for the Trijicon RMR or other red dot sights with the same footprint. This aftermarket slide for the GLOCK 19 Gen4 also features the Primary Machine UCC slide cuts to reduce weight and give you better traction when racking the slide.
