The YHM Nielsen Piston in 9mm Luger with 1/2-28 threads (brand part number YHM-2060-28) is a booster piston built for YHM’s own YHM-2055 booster housing as well as many popular pistol suppressors. Machined from 17-4 stainless steel and heat treated for durability and corrosion resistance, it gives suppressor owners 10 adjustment points to zero out any impact shift caused by the host pistol. The 1/2-28 thread pattern is one of the most common on 9mm pistol hosts, making this piston a versatile fit across a wide range of suppressed 9mm builds. At just 1.40 ounces, it’s a simple, precise way to dial in point of impact on a booster-equipped suppressor setup.
