When using a suppressor on a semi-automatic pistol without a fixed barrel, you need a Neilsen device and piston for proper operation. This Yankee Hill Machine 9mm 1/2x828 Piston is constructed out of heat treated 17-4 stainless steel. YHM designed their pistons to be able to be easily changed out for use on their YHM-2055 Neilsen booster and many other popular pistol suppressors. Place this piston into your booster to allow the suppressor to move when your barrel unlocks, this makes your pistol cycle rounds and not jam. If you have a fixed barrel, then you can throw a fixed barrel spacer on this piston to keep it from moving. This piston has 10 adjustment points to zero any type of impact shift.
