CZ SP-01/P-01 Optic Milling

My second gun milled by Primary and I couldn’t be happier. LEO discount with lighting fast service and return.

Milled my P-01 for a Holosun 507k and applied cerakote. The 507k fits perfectly and allowed me to lower 1/3rd co-witness with factory sights. Very fast turn around. Work was flawless. EXTREMELY pleased with the result. Graphite black cerakote matched the factory black perfectly…

Precision work. Awesome job.

The machining that Primary Machine did is very clean. There isn't a gap or anything between the optic and the slide, both on the front and back of the optic. Very well fit. The CZ urban grey they recoated the slide with is a little lighter than what came from CZ, but that's a very small nitpick. I could hardly tell, until I put the gun back together and noticed the frame was a little darker. I imagine it's very hard to do exact color matches on that sort of thing, and it doesn't even bother me. Overall, keep doing what you do. It's clean work.

My SP-01 was milled for the Holoson 507k with Smith and Wesson Red Cerakote. I was very happy with the job and the turn around time (less than 3 weeks).

I had my P-01 cut for a Holosun 507K with Primary Machine's suppressor height back sights installed. The work is perfect, the optics is close to flush with the slide, the cerakote is flawless and sights look factory. With the 507K mounted directly to the slide, no plate, the mechanical height over bore is not affected as much and looks so clean. I could not be happier.

Outstanding service, turned out perfect.
