Assembled DLC Window Slide for Glock 17 Gen 3

The dlc window slide glock 17 is pure aggression in black diamond-like carbon. First, we machine it from 17-4 stainless. Then we mill deep side and top windows for weight reduction and killer looks. After that, we coat every surface in ultra-hard black DLC.

Next, we inshttps://glockslideshop.com/tall a match-grade barrel and all internals. Finally, we test-fire and ship the same day. As a result, the second your dlc window slide glock 17 arrives, you drop it on your Gen 3 or Polymer80 frame and go dominate.

Massive windows, razor-sharp serrations, and that mirror-black DLC finish shrug off holster wear. Same-day unmarked shipping. No FFL required.
