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 for Ruger® MKIV™ from TANDEMKROSS is the ideal upgrade to boost your control!

The oversized, 1911-style safety 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 Ruger® MKIV™ aluminum 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.

Please note: The "Cornerstone" installation utilizes a factory spacer included in your original Ruger box. This part is referenced on Page 23 of the original Ruger® manual.

Please note: Some modification of the grips may be required for proper fit on Hunter and Target models that use the target wraparound wood laminate grips with finger grooves.
