Sig P320 Optic Cut - Holoson 509t (not 509ACSS)

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.

PLEASE NOTE: THIS OPTIC CUT IS NOT COMPATIBLE WITH THE 509ACSS VULCAN.

    509t optic cut

    The optic cut performed on my Sig p320 is sized perfectly and is an accurate fit to the optic. It also arrived several weeks faster than the quoted lead times! I am thoroughly impressed with the workmanship from Maple Leaf Firearms and they will be my go to shop for milling and refinishing work!

    The entire process was super easy. I was kept up to date on the process and it arrived in the time frame given. The optic cut is amazing and tight. I will be sending more work their way!

    Perfect Cut

    Posted by Cam E on Aug 1st 2021

    Nice low cut, tight fit for the Holosun 509t. The recommended XS sights are a perfect match. The stonewash finish is awesome. I will be returning here for further slide work. Slide was sent back in the expected time frame, packaged very well. No complaints!

    Sig 320 509T Cut

    Posted by Kevin Aston on Jul 31st 2021

    Very nice.
    When I drop the 509 into the cut there is basically zero free play. As close to perfect fit as possible. The nitride refinish is very nice. They reinstalled my sights perfectly. The wait time for cut and finish was as stated. This cut makes for a very nice package and I plan to send them more 320 slides for the same treatment . Thank you

    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.
