The precision-machined heavy-duty slide stop is made from steel bar stock and heat-treated to achieve exceptional strength and durability. It guarantees an exact match to the frame for secure, consistent lockup, and it prevents any looseness or "play" that could affect precision. There's the standard .200" diameter pin and the oversized .203" pin that can be customized according to your desired fit, ensuring maximum accuracy. Both sizes are available in blued 4140 carbon steel or stainless steel, with a fine bead-blasted matte finish. The pad's fine-line serrations provide a secure grip for your finger to release the slide on the first pass.
