TK Cornerstone Safety Thumb Ledge for Ruger Mark IV

Oversized, 1911-style safety ledge
Enhances factory safety
Improves hand placement for better grip, control
Whether you’re a competitive shooter working to improve your speed and accuracy or a weekend plinker looking for better control over your pistol, a strong, proper grip is key. The new Cornerstone Safety Thumb Ledge from TANDEMKROSS is the ideal upgrade to boost your control!



Now available for the MKIV™, the oversized, 1911-style Safety Thumb Ledge, made from anodized aluminum, enhances the external factory safety, without modifying the internals of the safety mechanism. This drop-in part is easy to install and does not change the internal components of the gun. Installation of the Cornerstone Safety Thumb Ledge for Ruger® MKIV™ is also a great opportunity to remove the factory ambidextrous safety, which can pinch some users' fingers while shooting.

The aluminum Cornerstone safety ledge offers an ideal thumb placement for a secure grip and provides consistent hand positioning and helps to control muzzle flip. This is one of the best Ruger® MKIV™ accessories for competition shooters. Get your Cornerstone Safety Thumb Ledge today and lay the foundation for a better grip!

Please note: The Cornerstone installation utilizes a factory spacer included in your original box. This part is referenced on Page 23 of the original Ruger® manual. If you cannot locate this spacer, please contact TANDEMKROSS or Ruger® and we can assist you with locating one.
