1911 owners, these grip screws are a simple upgrade that makes a real difference in your pistol's performance and appearance! You get four stainless steel screws with a clean matte finish that look fantastic on any 1911. The included O-rings are the secret weapon - they prevent the screws from loosening during recoil, so you don't have to constantly retighten them during range sessions. These are compatible with all 1911 models including Colt and clones, working with full-size grips and slim grips that are at least 3/16 inch thick. The precision machining follows original 1911 ordnance specifications for thread pitch and diameter (0.150-50 UNS), so they fit perfectly without modification. Installation is straightforward using a T15 Torx driver, and the quality is immediately apparent when you handle them. Made right here in the USA by Challis Grips, a company known for their attention to detail and quality firearms accessories. These screws work particularly well with their hex drive grip bushing system for the most secure grip mounting available. Whether you're replacing worn-out original screws, upgrading for better performance, or just want a cleaner look for your custom 1911 build, these screws deliver both function and style. They're one of those small upgrades that shows you care about the details of your firearm maintenance and customization. Definitely worth it for any serious 1911 enthusiast!
