Our Iron Sight Slide for Glock 17A(R) Gen3 enables you to build a custom GlockA(R)-style pistol - or rebuild an old one - with a slide that sports distinctive customized cocking serrations. The unique front serrations aid in manipulating the slide under stress, especially for quick chamber checks AND for clearing the occasional jam. Both the front and rear serrations are cut to the same depth as the GlockA(R) factory slide serrations to ensure no loss in overall slide rigidity. The top edges and the front around the muzzle area are chamfered to reduce the risk of snagging on clothing and to make holstering the pistol easier.
