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.

    Going off my last review, I’m now realizing that the plate I received despite having the correct serial number engraved into it does not even look like the plate pictured. The rear sight looks different and does not have a hole for you to put a third screw into its place. Finally, while I think this intentional to not step on the toes of dawson precision, there are no tongues for the tongue and groove slots on your staccato’s slide.

    Horrible experience about every step of the way for this plate. When first receiving it my optic would not fit on the plate as the plate was too wide. I decided to just use a file and trim away some of the excess and it now fits. However, Every time I need to remove it, I need to pry with a brass tool as it’s stuck. Why am I taking the optic off so much? Because this plate chronically becomes loose. Per their instructions of 10inlbs and VC-3 the plate becomes loose about every 400rds for me. I then started torquing up to 25inlbs and using blue loctite and that lasts me about 2,500rds until loose again. I shoot 1k rds a month and this has become so annoying that I am contemplating selling the 509 ACSS so I can just use an actual good dawson precision optics plate with a 509T.
