The dlc window slide glock 17 with your choice of barrel is pure aggression and function. First, we machine it from 17-4 stainless. Then we mill massive side and top windows for weight savings and heat dissipation. After that, we coat every surface in ultra-hard black diamond-like carbon.

Next, you pick flush or 1/2×28 threaded match barrel. Finally, we install all internals, test-fire, and ship the same day. Consequently, the second your dlc window slide glock 17 arrives, you drop it on your Gen 3 or Polymer80 frame and go straight to work.

Deep windows, razor serrations, and that mirror-black DLC finish shrug off daily abuse. Same-day unmarked shipping. No FFL required.
