Non-Marking Drift For Sights & Pins This handy little punch is made for just one purpose . . . to drive the front sight in or out without marring it or the barrel. We first tried Brass, but as you know, it leaves a "Brass tracking" wherever it rubs. We then tried fiber, but after a few hard blows it shatters. NYLON doesn't mark the barrel or sight, nor does it shatter or lose its shape after hard and prolonged use. Works Great on Glock , 1911 , Colt and Morel. A great alternative that wont scratch your finish. Sold in a set of 3.
