A knurled-grip 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. Knurled texture front and rear gives a positive hold on press checks and when racking. Assembled with a crown-cut black nitride barrel, 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.

What's included

• Knurled-grip slide, RMSc optic cut, black nitride over 416 stainless
• Optic cover plate, installed
• 9mm crown-cut black nitride barrel
• Tall (suppressor-height) polymer sights, installed
• 3CR Tactical slide completion kit — striker, extractor, safety and recoil assembly
• 3CR Tactical lower parts kit for the Glock 43 and 43X — ships with two magazine catches, one for each frame length

What you'll need to supply

• An RMSc-footprint optic, if you want one — the cover plate ships installed so it runs iron-sight-only until then
• A frame, magazine and the remaining lower components. This is an upper and a parts kit, not a complete pistol.

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