Sig P365 Optic Cut - Holosun 407k/507k

(65 reviews) Write a Review

Add a Holosun 507k Optic Cut as a standalone upgrade to your Sig P365 slide.

This Optic Cut allows you to mount a 507k 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.

    SIG P365 OPTIC CUT - HOLOSUN 407K/507K

    Great job done! I would definitely recommend Maple Leaf for Optic cuts. I have since taken my P365 to the range and have been very please with the quality of the work and the optic itself. As for the shipping, it was straight forward with no glitches.

    Wonderful Job and Faster than Expected

    Posted by Austin on Nov 8th 2021

    I am really happy with the work they did. I had them do the Black Nitride after they milled the slide and I am really happy with it. The Black Nitride looks really good. It was only an extra $25 to do the Cerakote job. I couldn't decide on the color options they had. I wish they had more pictures of the colors and maybe examples of the colors on the slides. I possibly would have had them do that if I would have seen and felt more confident in the color options.

    P365 optic cut and Holosun 407CK optic

    Posted by John Greene on Nov 4th 2021

    Maple Leaf was fantastic with the quality of craftsmanship work with the optic cut and install of the optic. Turn around time was great. 2 weeks on the slide work and 3 day delivery on return shipping. Great customer service with follow up information on receipt of slide, in process of slide cut up date and shipped information. I will use them again on other projects.

    P365 Holosun Optic Cut

    Posted by Roger on Oct 13th 2021

    First impression right out the box, outstanding! Looked it over for fit and finish, nothing out of place. Truly impressive, zeroed at 15 yards with zero issues and the craftsmanship continued to hold up as good as it looked. Fast forward two months later and I now have 500 rounds through the gun and it’s been my daily carry for a little more than the last month. Maple Leaf has done themselves good! No issues with reliability, zero or fit and finish. The highest compliment I can give is that I will give them my hard earned money again and I tell my friends that you can trust your life on these folks work.

    Posted by Mark Schumacher on Aug 8th 2021

    I sent mu third P365 slide in for the Holosun 507K optics cut. Once again I received it back quickly, 16 days and the work was great. The fit is extremely tight and the works looks great. Maple Leaf is a great business to work with, thanks.

    Holosun 507 Optics Cut on Sig P365

    Posted by Mark Schumacher on Jul 25th 2021

    This is the second slide that I sent for the same work, it's a friends and I loaned him the upper from my spare 365 so he could carry while it was being machined. As with the first, it's a great job, extremely tight fit so the optic won't move, great machining skills and no damage or nicks to the rest of the slide. Turn around time was even better this time, from Illinois to Texas and back in 18 days. Can't say enough about the great workmanship and customer service from Maple Leaf Firearms.
