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.

Optic Cut
Again I'm very satisfied with the work performed. Highly recommend John's work. The optic fits like it was part of the slide.

Holosun 407k
Although, the cut is precisely perfect fit, i would have rate 5 star if they thread to the original Sight metric thread screw, they use standard thread and does not seat flush with the sight screw holes, email was not response when i first sent the slide, although after received the slide back and does quick response with issues i have with the slide, definitely go back if they modified to it original metric thread

507k set back cut
P365 came back quickly and all mounted up. It ate 100 mixed rounds on the testing range trip with no issues. Looks great too, fit and finish are perfect.

Sig 365 Optic cut
Outstanding work! Mounted a Holosun 507kto my slide went to the range the same, everything worked as advertised machining was perfect no need to refinish the slide. From the time I mailed my slide until it was returned wash about 3 weeks.
