Fit perfect and works Great


I bought one of these to finish my P80 build. It fit perfect and really made it very easy to complete the build. The frame needed a little fine tuning to get it to cycle correctly, because I left the rear rails a little thick, but that is not the fault of the slide. I have since finished another P80 in FDE and just move the slide to whichever frame I feel like using. I will buy another one when they are available in FDE, (and I have the $$$). It's stock Glock, how can you go wrong!

Very Nice


Purchased a G22 upper for my Polymer80 frame. The 40 S&W makes perfect sense to me. And... there are optional conversion barrels in 9mm if I would like to shoot a lighter round.

G17 upper


Timely shipping, perfect condition, great customer service!
