Sig P320 Optic Cut - Holoson 407c/507c/507COMP/508t

(10 reviews) Write a Review

Add a Holoson 407c/507c/508t 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 Holoson 407c/507c/508t 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 optic 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.

*Optic not included.

**Not compatible with our RMR Cover Plates.

    Quality cut

    Waited about half a year and a couple thousand rounds to come and write this. Still holding zero perfect, these guys are the real deal. If you're in TX they do drop offs and even showed me around their workshop. Cool dudes and awesome work.

    Maple Leaf has completed optic cuts on four slides and their work is top notch. Balancing a reasonable turn around time while doing quality work is always a challenge; however, Maple Leaf has done it every time.

    The Maple Leaf Team did a fantastic job modifying my SigSauer P320 compact slide to accept my Holosun optic. Very easy to order, their work was efficient and very professional. I highly recommend them and will definitely use them the next time.

    Workmanship appears to be excellent. Slide retuned with the Holosun 507C mounted, everything looks perfect. Took the pistol to the range, worked great. 3 week turnaround time, plus shipping. I am happy.

    Holosun cut

    I couldn't be happier with the quality of the work. My optic fit snug with zero "wiggle room". I will only use Maple Leaf for my future builds. The communication was great, speed of work was exceptional given all the covid issues, and the quality of work was absolutely outstanding!
