Sig P365 Optic Cut - Holosun 407k/507k/EPS/EPSCARRY

(85 reviews) Write a Review

Add a Holosun Optic Cut as a standalone upgrade to your Sig P365 slide.

This Optic Cut allows you to mount a 407k, 507k, EPS, or EPS Carry sight directly to your P365 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 507k 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.

    PERFECTION!!! Both for the optic cut and the nitride refinishing. Have already recommended others to use MLF for their needs. Will most definitely be using again.

    Very happy with the great work. The turnaround time was less than one week. The Holosun optic fits perfect. A great upgrade for my old eyes.

    Sig P365 Holosun 407K Optic Cut

    Posted by Russ on Jan 2nd 2023

    Purchased optic from Maple Leaf and had them mount on P365. Great fit, precision cut. Delivered when they said it would be and came back in a box w/custom cut foam. Also came back with the Holosun box. Definitely recommend

    Holoson Optic Install on Sig P365

    Posted by Tomi Ferguson on Nov 28th 2022

    I had Maple Leaf Firearms install a Holosun 407K Green Dot optic on my EDC (every day carry) Sig Sauer P365. They received my slide and optic in the mail on November 10th and I received it back today, November 21st with a perfect install, right before the holiday! The online service ordering was simple & easy and I appreciated the great communication throughout the process. I could track my install progress online and immediately got a tracking number when it was shipped for return. I will definitely be using them for all of my husband & my firearms customization needs.

    Optic Cut and Refinish for P365

    Posted by Eric L on Oct 27th 2022

    This is the 3rd slide that Maple Leaf has completed the optic cut and refinishing. They always do superb work and the refinish black nitride makes the slide look brand new. I am a satisfied repeat customer.
