Rugged Suppressors Internal Shoulder Suppressor Piston Copper 1/2-28

The Rugged Suppressors Internal Shoulder Suppressor Piston is an accessory for suppressor setups on the Glock 43 and Sig P938. It is designed to maintain reliable function on these hosts by replacing the piston used in an internal shoulder configuration.

The piston uses a non-slotted design that creates a full-circumference gas seal, which the manufacturer states is intended to reduce gas blowback. It is machined from 17-4 stainless steel and carries a copper finish that makes it easy to identify when configuring or servicing a suppressor. The thread pitch is 1/2-28 tpi.

The piston is listed for the Glock 43 and Sig P938 and is intended for compatible barrels with internal shoulder requirements.
