Sig P320 Optic Cut - Trijicon RMR

(8 reviews) Write a Review

Add a Trijicon RMR Optic Cut as a standalone upgrade to your Sig P320 slide, or in conjunction with our other slide milling options.

This Optic Cut allows you to mount a Trijicon RMR sight directly to your Glock slide with two included #6-32 screws.

The cut features a precision CNC machined pocket directly in front of the Sig factory rear sight dovetail. By design, the RMR will fit tight within this pocket, preventing the sight from moving in any direction, ensuring your optic remains zeroed in even under the harshest conditions.

This product includes the Optic Cut only.

*Trijicon RMR not included.

**Not compatible with our RMR Cover Plates.

    Trijicon RMR Cut

    Posted by Dave on Jun 1st 2020

    I was a little apprehensive about mailing my slide out as I'd never had one milled before, and I had a few questions. I sent an email asking them, and even though they were extremely busy, I got a lengthy personal email back answering all of them and explaining the whole process. I ended up sending my slide in, and received it back about 3 weeks later. The cuts are perfect and my RMR mounted right up with the provided screws. This is a great company with great communication and a great product...they are definitely now my go-to for any future milling jobs I need done.

    Sig P320 VTAC RMR cut

    Posted by S. Paperd on Feb 22nd 2020

    Initial communication with John was great. The prices and turnaround times are hard to beat. Most of the more well known companies are so backed up that turn around times are in (or close to) double digits where as here it was only a couple weeks. The actual product was clean and professionally done. My RMR fit like a glove with no extra space or overcutting.

    My only complaint was lack of communication after I sent my slide in (no verification of receipt, etc). When I eventually emailed for an update (after about 3 weeks), I never got an email back; I just got a auto notification that my slide was en route back.

    This work was done for my duty gun and Ive already had coworkers ask for Maple Leaf's information. I am very impressed and I highly recommend them for any milling and custom work!

    Sig P320 Compact optic cut for slide

    Posted by Christopher Eppley on Jun 20th 2019

    I sent in my Sig P320 Compact slide to be cut for an optic and then to be refinished with black nitride finish. I could not be happier with how this slide turned out. The communication with Maple Leaf Firearms was excellent and the turn around was very quick. With shipping both ways, my slide was back inside of three-weeks! The optic cut was expertly completed, the price was very fair, and the black nitride finish is, in my opinion, better than the factory finish on this slide was. I'm beyond pleased and will certainly send them more slides to be worked on!
