Accessories for Ruger 57

The Ruger 57 is a full size pistol chambered in 5.7x28mm, a small and fast cartridge that gives the gun light recoil. It comes with an optics cut in the slide, so a red dot is the upgrade most owners look at first.

Plates for the cut

We stock two Outer Impact plates. Type C is for dots that use the Trijicon RMR, C-More RTS or Docter base pattern. Type S accepts Shield RMSc, Leupold DPP and Holosun K-series footprint optics, the smaller pattern used by many compact dots.

Why change the factory plate

A plate machined for one footprint lets the optic sit flat and low, without stacked adapters. That keeps the dot close to the bore and helps it hold zero shot after shot.

Both versions are listed on Optics ready plates for Ruger 57.

Frequently asked questions

Will a type C plate take a Holosun 507K?

No. The 507K uses the K-series pattern, which needs type S.

What is the plate made of?

CNC machined aluminium, made in the USA by Outer Impact.
