  • JSD Supply Patmos Arms Judah 26 - Glock 26 Compatible Slide

    The Patmos Arms Judah 26 slide is G26 compatible. The slide moves during the operating cycle and houses the firing pin as well as the extractor. This slide’s impressive design offers a real advantage for users. It allows them to do a fast press check, before and after firing. A user’s weak hand can use the front and rear serrations to grip the slide and move it to the rear until the chamber is in clear view. When done correctly, this ensures that a round is properly chambered without the hand getting anywhere near the muzzle of the pistol.
