Description
The 1/2×28 Internal Shoulder is for use with the Sig P938, Sig P320 and Glock 43. The piston uses a non-slotted design creating a full circumference gas seal. This drastically lowers gas blowback for a more enjoyable shooting experience. Machined from 17-4 Stainless Steel and heat treated this piston is built to last. Pistons are generally used with a booster system on handguns. When using a piston on a fixed barrel platform such as a carbine or subgun the spring must be replaced with a Fixed Barrel Spacer. For information on what mounts/accessories should be used with your host firearms check out the Pistol Suppressor Attachments Guide.
