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.

Easy install
The Thumb Rest and Safety Thumb Ledge were easy to install. My Ruger Mark IV 22/45 Target now compliments my CZ Shadow 2 for shooting Steel Challenge.

Safety Thumb
Bought the Safety Thumb in Red & it looks & feels good in hand. Will be test shooting very soon so I can't give a update on that just yet. Otherwise, very pleased with this item on my weapon the Mark IV Tactical

heads up on install
Instructional video was good, thumb ledge safety is perfect, and I certainly needed to remove the right-hand safety, but one thing that should be in the video: Immediately after removing the right-hand grip, take out the magazine assist, the safety spring and the plunger. These are at the bottom of the grip frame. If you don't, they surely will go "boing," as mine did, to my surprise. Two of the pieces ended up on my rug -- 10 minutes to find them.

Cornerstone safety
Customer service outstanding! Must have on my Ruger Mk4 Target 5.5 inch! Perfect fit and finish! Went with black on my Stainless Mk4! Looks like it came with gun! Thanks Donny

Ledge safety
If you like to shoot thumb riding the safety, like on a 1911. This is the way to go. The thumb stays clear of the slide lock and the wide ledge helps make the grip more consistent. Combine it with the thumb rest for the weak hand and the gun becomes much more stable in my opinion.

Cornerstone Saftey
The Cornerstone thumb ledge solves a major problem of accidentally engaging the safety on the MK IV.
