Some upgrades add speed, some add accuracy, and some just fix the one thing about a pistol that nags at you every time you pick it up. The Pinnacle Safety from Creekside Custom belongs to that last group. It is a purpose-built replacement for the factory safety on the Ruger MK IV, made for shooters who want the thumb to land in the same comfortable spot every time. The goal is a consistent, comfortable and repeatable thumb position every time you shoot. Consistent hand placement matters for accuracy, recoil management and speed, and the Pinnacle Safety offers a repeatable reference point so the same grip comes back each time the pistol is picked up. That is useful whether you are chasing faster stage times, tighter groups or just a more comfortable range session, and it leaves your attention on the sights, the trigger and the shot. This sounds like a great upgrade for Steel Challenge and similar shooting sports. Construction is straightforward. The safety is precision-machined from a single piece of 17-4 stainless steel, and its ergonomically rounded profile guides the thumb naturally into position.Installation is a drop-in job. Replace the factory safety with the Pinnacle Safety, and no permanent modifications are needed. The Pinnacle Safety costs $115, and it is available in stainless steel or black.Creekside Custom Pinnacle Safety for Ruger MK IV key features:Precision-machined from one-piece 17-4 stainless steelFits Ruger MK IV pistolsNo permanent modifications requiredSimple, easy installationErgonomically rounded design for natural thumb placementImproves consistency, comfort and controlAvailable in Stainless Steel or BlackDurable construction built for competition and everyday useMade in the USAMore details can be found here: https://creeksidecustom.com/pinnacle-safety-for-ruger-mkiv/ Do you use a consistent thumb position on your 22/45, and would a different safety help?
