Appendix carry claw/wing by RCS.
The claw is designed to sit behind the belt and rotate the grip in to the body. It is designed specifically for appendix carry, but it will work the same, regardless of position.
Made of injection molded plastic, these claws are much more durable than the kydex versions.
This claw was designed by RCS (Raven Concealment Solutions) for the Eidolon. The mounting holes are 1.5cm center to center. This claw sticks out the farthest to the side from the holster. It is fixed in position, and in the amount of grip rotation it provides.
We can make no guarantee that it will fit your holster.
