Description
The Ed Brown 1911 Government Slide is engineered for shooters tired of dealing with awkward optic mounting solutions. This stainless steel slide arrives pre-cut specifically for the Trijicon RMR platform, eliminating the need for custom machining or bulky rear-mounted brackets that compromise your 1911's profile and handling.
Why the RMR Cut Matters
Standard 1911 slides aren't wide enough to direct-mount RMR-style optics without additional hardware. This creates either unsightly cuts in the rear sight area or forces mounting plates that sit too high and throw off your sight picture. The Ed Brown solution cuts straight through that problem. The factory-cut RMR footprint integrates cleanly into the slide's rear, delivering a low-profile setup that looks and shoots like purpose-built work. No trips to a gunsmith, no guesswork on fitment.
Quality You Can Trust
Reviewers consistently praise the fit and finish of Ed Brown slides. The machining is clean, tool marks are nonexistent, and the stainless steel construction handles the rigors of practice and competition alike. The slide features front and rear cocking serrations for positive racking whether you're clearing a malfunction or working from the bench. Most users report minimal fitting needed when installed on compatible 1911 frames, with some requiring just light lapping to dial in a perfect rattle-free fit.
Built for Performance
Users running this slide report noticeable accuracy improvements and reliable performance through hundreds of rounds. It's become a go-to choice for competitors in bullseye shooting and serious precision rifle applications. The combination of professional machining, optic-ready design, and Ed Brown's reputation for durability makes this slide worth the investment for anyone looking to upgrade without complications.

Frequently Asked Questions
Will this Ed Brown Government slide fit my existing 1911 frame?
This slide is designed to work with standard 1911 Government-sized frames. Most users report it fits directly with minimal to no fitting required, though some frames may benefit from light lapping to achieve a perfect rattle-free fit. Frame tolerances vary, so verify compatibility with your specific frame before purchasing.
Does the RMR cut come with the mounting plate?
No, this is a stripped slide only. The RMR cut is machined into the slide, but you'll need to source the Trijicon RMR mounting plate and optic separately. The pre-cut design simply saves you the gunsmith work of creating the cut yourself.
What optics will fit the RMR cut on this slide?
The slide is cut specifically for Trijicon RMR-pattern optics and compatible mounting plates designed for that footprint. It's not compatible with standard dovetail sights or other red dot footprints like Shield RMSc or Holosun HS507.
Can I use iron sights with this slide?
The RMR cut removes the traditional rear sight area, so you won't be able to install standard fixed sights. However, many shooters set up co-witness height front sights that work alongside their RMR optic for backup aiming or if the optic fails.
