A stripped windowed slide for the Glock 43 and 43X, machined from 416 stainless and finished in salt-bath black nitride. The lightening window cuts reciprocating mass and shows the barrel through the top of the slide; the RMSc footprint is cut directly into the slide, and a cover plate ships installed so it runs iron-sight-only until you mount an optic.

What's included

• Stripped windowed slide, RMSc optic cut, black nitride over 416 stainless
• optic cover plate, installed

What you'll need to supply

• A slide completion kit — striker, extractor, safety and recoil assembly
• A 9mm barrel and sights
• A frame. This is a slide only, not a complete pistol.

Fitment — Glock 43 and Glock 43X, and third-party frames built to the same pattern. Optic cut is RMSc footprint (Shield RMSc, Holosun 507K/407K, Sig Romeo Zero and similar). Optic screws are 6-32.

Also available without the window cut.
