All slides are evaluated when they arrive to determine that an optics cut can be safely milled into the slide. If we determine your slide cannot be upgraded, we’ll send it back to you at no charge and issue a complete refund.
Any 2011/1911/STI series 80 slide that has a safety plunger/firing pin block CANNOT be milled for any optic or adapter plate due to the cut going into the safety plunger/firing pin block cavity. The only exception is the Lionheart Regulus due to the cavity for the firing pin block not extending into the cut area.
We cannot mill any .22 caliber 1911 slides.
**The pictures of each modification are an example of what only choosing that modification will look like on the slide. Modifications performed may not look exactly as depicted depending on your slide model and the combination of serrations, windows, and/or pockets you chose.
**The CHPWS EDC-RMSc/EDC Enclosed/C&H Max, Holosun 407K / 507k/EPS, Shield RMSc, Sig RomeoZero/RomeoZero Elite/RomeoX Compact (Romeo Zero Pro and R cannot be direct milled) Vortex Defender-CCW (Defender-ST and XL cannot be direct milled) and Trijicon RMRcc can be direct milled to your slide without an adapter plate. All other optics must be mounted with the CHPWS cross plate.
**The Agency Optic System (AOS) cut can only be milled in slides that have no rear sight dovetail or a standard rear sight dovetail. This cut cannot be milled into slides that have a BOMAR rear sight cut or other adjustable rear sight cuts that are low at the rear of the slide and cut into the firing pin retaining plate.
**All 1911/2011 milling requires the rear dovetail to be milled away. Most CHPWS cross plates and AOS plates incorporate a built in back up iron sight.
** Most 1911/2011/STI slides are milled to the depth of the base of the rear sight dovetail or BOMAR cut for direct mill or cross plates. Slides with a shallow rear sight dovetail or no dovetail are milled to a depth of .200″ from the top of the slide if possible. This is to ensure the cut is flat and screw holes are milled properly. For slides with a deep dovetail this can mean some thinner base direct mount optics may have the bottom of the window slightly below the top of the slide and make optic integrated rear sights sit too low to be usable with stock front sights.

Got a rmsc cut on my 1911 solid turnaround time had issues with UPS on the first time around, reached out C&H said they send it out as soon as it returned shout out Thomas for helping me out got the slide back 2 days later. The cut was nice and flush. Threads were good and had no issues with the screws of my optic hitting the extractor. No issues with backing out either after 1000 rounds. Solid customer service,good turnaround, Good price and good quality work.

Decided to go the red dot route and sent in my 1911 slide for a Rmsc direct mount cut. Super fast turn around in 8 days! The sight was mounted when I received it and I then removed it to confirm the 4 recoil studs were there. Sure enough the milling cut was perfect. The 1 degree slope needed for 1911 slides was perfect as the red dot sighted in great without running out of elevation. I’ll be sending in more slides.

Quick turnaround! Consider finish sensitivity.
C&H milled my Dan Wesson Specialist with a C&H cross plate for RMR.
The plate is cut low. My sight index is the same as before. I appreciate that C&H pre-installed my hardware and provided great instruction on torque spec, thread locker, and sealing.
Slide came back with cloudy staining on the OEM finish. Dan Wesson duty finish is sensitive to sensitive to harsh chemical strippers, strong degreasers, and ultrasonic cleaners.
Plate cut left a 1mm fin protruding near the breach face but it is not sharp and would be difficult to file down without leaving visble slide damage.

Sent three client slides for milling. Two received the AOS sight plates for RMR type sights. The fit and function are perfect. The plate will be around .075″ forward of the standard rear edge of the slide, allowing blending for a build. The rear sight picture is slightly above the deck of an RMR or 507 sight. The plate and cut are deep enough to allow a sight pickup not far above traditional irons sights.
The third slide is cut for an EPS Carry sight, giving 3/8″ from the rear of the slide. Again, allowing for blending, but not for mounting a rear sight unless you mill the rear corner and replace with a custom insert.
Having C& H mill the slides saves time and the cut is with radius, not straight milling across. All studs are milled into the slide, well thought out.
