Holosun K-series footprint standard

Holosun K-series footprint standard

Paul L. |

Holosun K-serie footprint standard consists of two sockets in the front. There are also two screw holes in the lower part of the sight.

This standard is used for red dots of all sizes: red dots designed for full size pistols, for compact sized pistols and even for subcompact sized pistols.

Footprint pattern

How does the Holosun K-serie footprint pattern look like? The scheme with all details are above.

  • there are two sockets in front, distanced from each other 17mm [0.66 in], and
  • there are also two screw holes in the rear of the footprint that allow fixation of the red dot to a plate or red dot mount 

K-Serie footprint vs Shield RMSc footprint

The footprint is very similar to Shield RMSc footprint standard. But only similar, not the same. There are some differences between those two footprint standards.

  1. Holosun K-serie footprint does not have rear slugs, and
  2. Holosun K-serie footprint uses more shallow slugs in the front compared to Shield RMSc footprint.

Technically its possible to modify the Shield RMSc footprint to work with Holosun K-serie footprint red dot, but it is not that simple. You will need to remove the rear slugs on the plate or mount, and you will also need to sand down the front slugs slightly.

You can however use also some of the footprint adapters to get to the Holosun K-Serie footprint. View them here.

Mounting

If you want to install red dot that is compatible with Holosun K-serie footprint to your pistol, you have two options: plates and mounts.

  • plates work with optics ready models with optic ready cut in the slide, 
  • mounts work with standard models and they function as a replacement of rear sight in the dovetail cut.
