The True Precision Slide for Glock 43 with RMS Cut in copper finish is a US-manufactured replacement slide designed for shooters who want to upgrade their carry gun with modern optics capability. Built from 17-4 pH stainless steel and heat-treated to specification, this billet-cut slide gives your Glock 43 a clean, professional appearance while adding the practical advantage of a milled optic mounting surface. The copper finish sets it apart visually while the precision engineering ensures reliable performance for everyday carry, training, or personal defense.

What makes this slide stand out is True Precision's approach to the optic cut itself. Rather than machining in additional mounting lugs, they've engineered the RMS cut to accept Shield Arms' full lineup—RMS, RMSc, and RMSw—while also fitting popular alternatives like the Holosun 507K, Sig Romeo Zero, Leupold Delta Point Pro, and JP Enterprises JPoint. That design choice means you have genuine flexibility in your optic choice without modification or adapters. An anodized black optic cover plate and mounting screws are included, so you can run the gun unmounted if you prefer, or swap optics down the road as your needs change.

True Precision operates right outside Atlanta and manufactures everything domestically in partnership with American suppliers. The slide features aggressive scalloped and reduced front edges with side and top cut windows that balance aggressive styling with functional weight savings. If you're building a custom Glock 43 or upgrading a well-worn carry gun with a modern optics-ready upper, this is a solid foundation from a maker focused on defense-grade quality.
