Most Helpful Positive Review C&H Plate - HOLOk
I bought the C&H Precision Works HOLOk plate for my double stack MOS Glocks (G17/G19/G45). I haven't used it yet but I run C&H plates on almost all of my MOS Glocks including my 43X. I thought it would be a good idea to get the HOLOk plate in case I want to mount a 407k/507k on my double stack MOS G...

Most Helpful Negative Review Quality and well-made but inadequate design
C&H makes a quality product (reason for the 2 stars) but this particular plate for the 43X/48 MOS mounts the RMR/SRO only by the two mounting screws. The plate isn't long enough to reach the two mounting holes in the front of the optic. You may never have an issue, but for a slide mounted optic, e...

Wanted to love these

by YankeeBluejeans, Verified Owner from MN, United States Written on March 22, 2025
These plates look great, but are NOT duty/mil grade. Their customer service is meh at best, absolutely horrible at worst. Just do some online searching before you buy.

So, my optic took a bump during training and everything loosened up. It was properly torqued to spec and thread locker was used. Since I can't live with this I started torture testing three guns with three C&H plates. They all failed to be what is best described as bombproof. So disappointed because I wanted to believe in the company.

Too late to get a refund and C&H doesn't stand behind their products. Their T-nut concept seems great but it's not robust or durable. Frankly, I would take my chances with MOS plates than this overpriced trash.

Bottom line: If your pistol goes in a holster, look elsewhere.

Superb for a duty Glock

by YankeeBluejeans, Verified Owner from MN, United States Written on February 8, 2025
The V4 mounting plate from C&H is the best you can buy. It's spendy but the quality is there and it's bombproof. If keeping weight low matters, this design helps.

Fit and finish is top notch. It comes with all the screws you'll need and they all have threadlocker pre-applied. Be sure to dry fit all parts so you'll use the longest T-nut screws without bottoming out. The stainless steel screws mount the plate to the gun. Torque everything to 12-15 in/lbs.

Great product

Far better than the MOS plates or the Vortex plates. Very sturdy and a rock solid platform.

Very high quality, sits on G43X MOS very snug...

by Crimsus, Verified Owner from TX, United States Written on February 8, 2024
I purchased this for use on my G43X MOS. The adapter plate is designed and machined very accurately. The plate sits in the MOS cutout perfectly with no noticeable wiggle room. I mounted my Holosun 507K onto the plate and installed the screws. The optic sits level and there are no gaps between the optic and the adapter plate.
Pros:
  • Well designed with good tolerances.
Cons:
  • None
Best Used for:
  • Works with G43X MOS.

perfect for mounting the Holosun 507k/407k

by johnchip, Verified Owner from CT, United States Written on December 27, 2023
The C&H Precision Weapons v4 MIL/LEO adapter plate for the Holosun 507k/407k does exactly what it says. Its a high quality plate and easy to install. I like how it is pretty low profile so the optic sits almost flush. Great for 1/3 co-witness on my Glock 43X MOS with ameriglo GL-351 sights. I actually used it for mounting the 407k. I'd recommend this adapter plate and any adapter plate made by C&H Precision - I've had nothing but great experiences with their products.
