Sig P320 Optic Cut - Holoson 509T

(2 reviews) Write a Review

Add a Holoson 509T Optic Cut as a standalone upgrade to your Sig P320 slide.

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.

    Sig P320 - Holosun 509T Optic Cut

    Posted by Jason on Jun 21st 2021

    I sent my P320 full size slide in. I had forgotten to include my order number with my slide. I let Maple Leaf know, they were very understanding. The slide was milled extremely well, the nitriding was also don very well. The slide was mailed back expediently. I am very happy with my P320 slide, the 509T is a perfect fit and I am happy to report that it shoots extremely well and reliably. Great work Maple Leaf! I'll be using your services again for my next build!

    Overall service was excellent. The slide, with mounted optic and sights was returned ahead of the estimated lead times and the quality of the work was outstanding.
