TANDEMKROSS Cornerstone Safety Thumb Ledge for Ruger Mark IV 22/45

The TANDEMKROSS Cornerstone is an oversized, 1911-style thumb ledge in anodized aluminum that replaces the external factory safety lever on the Ruger Mark IV 22/45 without changing the safety's internal mechanism. Your thumb gets a consistent resting spot for a higher, firmer grip and better muzzle control.

Installing the Cornerstone also lets you remove the right-side ambidextrous safety lever, which can pinch some shooters' hands.
