Below are the best Holosun Red & Green Dot sights you can mount on your Sig P226 or Sig P229 Optics Ready Version. These optics will fit only on the Sig P226/229 with a Romeo 1 Pro Cut. These optics are offered at the best price with free shipping.

To learn more about each optic and how to find your optic cut read our Sig P229/226 Optics Fitment Guide here.

To mount the Holosun RMR Footprint optics you will need to use 6-40 screws but we recommend getting this CHPWS Sig P226/229 Filler Plate which includes all hardware. This plate give you extra reliability because it makes contact with the front and rear of the slide cut for extra recoil force distribution.

To mount the Holosun K Series optics you will need this CHPWS Sig P226/229 to Holosun Modified RMSc/K Series Adapter Plate.

If you want to mount a Holosun 509T and want a dedicated plate get this CHPWS Sig P226/229 509T Adapter Plate.

This applies to the following models Sig P229 PRO, Sig P229 Legion Compact, Sig P229 Legion Full Size, Sig P226 ZEV, Sig P226 PRO-Cut.
