DRY-FITTING DISCLAIMER:
At C&H Precision, our products are designed and manufactured to meet tight tolerances. Installation can be affected by variations in your plate, hardware, optic, and firearm tolerances. For safe installation and to prevent potential damage to any component, we advise dry-fitting all parts before a full installation. If any problems arise during this process, please reach out to our Customer Service via our contact portal.

IRON SIGHTS DISCLAIMER:
When making aftermarket firearm modifications, factory components can often become obsolete, particularly when mounting optics on the slide, whether through direct milling or using a plate. Achieving the correct height for low co-witness iron sights depends on factors such as the firearm type, mounting plate, optic, and slide cut. For assistance in determining the appropriate iron sight height for your specific setup, please contact our Customer Service team through our dedicated contact portal.

    After my first review the company reached out to me and resolved my issue. Kudos to the management for doing that. Everything fits fine now on my XDM ELITE.

    I should’ve listened to reviews about the t-nuts not fitting properly. I tried to file down to get it to fit but will not fit properly! Don’t buy@ this price when parts don’t fit properly.

      Dear Valued Customer,

      We sincerely apologize for the fitment issues you were experiencing. Looking back at your order history we did have a small batch issue with these plates when you ordered them. We have fixed the issue since then. I will reach out to you directly about fixing this issue immediately. Again I apologize for the inconvenience.

    Perfect fit, excellent finish and all required hardware included. I installed this on my XDM Elite 3.8 OSP for the Holosun EPS (same footprint for 407K).

    First, I purchased a plate from another vendor since this plate was out of stock. I had issues with that plate, The factory Holosun optic-to-plate screws did not fit–they were too small. Second, there was no finish on the plate it was discolored and starting to rust. I acquired the correct size of screws from my gunsmith, The threads were correct but the bevel of the screw head did not match the optic recess so the screwheads were just above flush.

    Once this plate came back in stock, I ordered it along with a spare set of screws (just to have spares). The plate is nicely finished and the Holosun screws fit perfectly. I installed the plate per C&H’s instructions, 10 in pounds for both plate to slide and optic to plate using the included thread locker.

    I like the clever design using T nuts which provides more threads for the screws and allowing a lightweight aluminum plate instead of steel. My next plate will definitely be a C&H P.

    Excellent fitment for an XDM Elite 3.8″ 9mm, and Holosun EPS (407k footprint). I was going to grind the oem Springfield plate and make it work, but these plates retain another lug to locate the Holosun and add strength to holding the optic to the plate. Very fast shipping as well, thanks!!
