Most Helpful Positive Review Holoson 507 on Sig P229
Mounted the Holoson 507 perfectly on my Sig P229 Pro. Solidly built
Most Helpful Negative Review C&H Filler plate
Plate does not made to tight enough tolerance to snugly take up the space between the front edge of the optic cut and the front of the optic itself. Needs tighter tolerances.

Poor fitment

by GunSmoke, Verified Owner from LA, United States Written on December 7, 2025
The underside slot insert is too short,does not fill the Romeo Pro cut fully.This allows some play in the plate ,therefore negating any displacement of forces off the mounting screws.One might as well directly mount the optics to the slide! DDP makes one that fits better and at half the cost.
Pros:
  • Light wt
Cons:
  • poor design of slot insert, price
Best Used for:
  • return

Works Great

by Bart LXIX, from IN, United States Written on March 16, 2024
Simple as it gets. Perfect fit and simple installation of a Holoson 507C on my pro-cut P226 slide. If you're looking to add an RMR footprint optic to your P226 than this is definitely what you want to use.

Just what is needed

by RB, Verified Owner from FL, United States Written on September 27, 2023
This is the perfect way to go went mounting a Trijicon or Holosun optic on a Sig P226 or P229 with a factory optics cut slide. Since the slide is cut for a slightly larger Sig optic, a Trijicon SRO or RMR isn't a "glove" fit on the factory optics cut. The C&H plate snugs up the install nicely. The online install guide & video is a must see, as it suggests steps that go further to insure a more secure install.
Now the Sig 6-40 fastener "issue". The C&H plate includes the correct screws for both a Trijicon or Holosun optic. The instructions recommend not reusing the fasteners should the optic be remounted or changed. The kit comes with only three screws for each install?!?. Knowing how hard it is to source these non-standard (SHAME ON YOU SIG!) screws, I would give this kit 10 out 5 Five Stars if only they would have included one more screw per install, which would have accommodate an optics change at a later date. Raise the price a bit if necessary. Otherwise, I don't know how you could improve on the kit.
Pros:
  • Solid Optic Install on P226-P229
Cons:
  • Come on Guys, just 2 more screws!
Best Used for:
  • Trijicon Optics on a Sig cut Slide
