The Rugged Suppressors OEM Internal Shoulder Piston (brand part number OP009) uses a non-slotted design to create a full-circumference gas seal, drastically cutting gas blowback for a noticeably more enjoyable shooting experience behind a suppressor. Rugged machines the piston from 17-4 stainless steel and heat treats it for long-term durability, then finishes it in copper for corrosion resistance and easy visual identification among a lineup of similar parts. The internal-shoulder design and 1/2-28 tpi threading are built specifically for use with the Glock 43 and SIG P938, giving owners of these compact pistols a piston sized to their exact host thread.
