A windowed Glock 43/43X slide assembly, built in-house at 3CR Tactical — machined from 416 stainless, finished in salt-bath black nitride, with the RMSc footprint cut directly into the slide and a cover plate installed. The lightening window cuts reciprocating mass and shows the barrel through the top of the slide. Assembled with a threaded 1/2x28 black nitride barrel with a thread protector installed, tall (suppressor-height) polymer sights, which clear a mounted optic and co-witness with most RMSc red dots, and the full 3CR Tactical slide completion kit.
