From: $50.00

This is for milling of the Glock MOS 43x/48 version slides ONLY. This upgrade will allow for direct mounting of Holosun 407k/507k/EPS/EPS Carry or Trijicon RMRcc** optics without the use of an adapter plate over the existing optics cut. For NON-MOS Glock 43x / 48 milling click here. 

**Upgrading to the Trijicon RMRcc footprint is an additional $40 due to the increased amount of milling required compared to the Holosun 407k/507k/EPS/EPS Carry.

    Great service, with extremely fast turn around. I originally went with a mounting plate for my 43X MOS and wanted something more streamlined and secured for a carry gun. After a lot of research I chose C&H precision, they didn’t disappoint.
    They contacted me when they received the slide to confirm the work and when it was finished and ready to ship. The slide looks great. Will definitely be sending more of my slides for work.

    I have been shooting handguns equipped with trijicon rmrs for around 3 years in a le / rangemaster capacity, plus for fun on the weekends. I had a 43x mos i didnt want to put a optic on because of how high they sat with trijicon mounting plates. I sent my slide to chpws to direct mill for a rmrcc and got it back in less than 2 weeks counting shipping time. The fit was perfect and the optic sits at a much more reasonable height. I put 20o rounds through it the first day and loved it. After the quality work chpws did i will probably never not use them to direct mill any slide for the rmr optic. Their mounting plates (I have several) are good, but the direct milling is excellent. Thank you chpws.

    Fantastic work. First time I’ve used this company, but I saw a picture on Reddit of a 43xMOS that they had milled out for an RMRcc and decided I wanted them to do my own gun due to the fact that they leave the rear dovetail in place instead of moving it infront of the optic like other companies. Got my slide back in a week and half, and the fit and finish is IMMACULATE. The fit is perfectly tight. You won’t regret it. Customer service line is top notch as well. Thanks guys!

    I cannot thank CHPWS enough for the work completed on my 43x Mos milled for the RMRcc. Not only will other companies refuse to offer this cut for this slide, I highly doubt anyone could do a better job. The cut is so precise, and the threads have such positive engagement that after a 1000 rounds and a weekend with Fieldcraft’s Gunfighter courses, the optic and screws are as if I just installed them. Follow the instructions that CHPWS suggests and I ASSURE YOU, you will have zero issues and be satisfied. Also, just got my 48 MOS back and I can’t wait to mount another RMRcc on it! 10/10 definitely recommend.
