The Nighthawk Custom FM Series plunger tube is precision machined from solid 11L17 carbon stock steel to ensure this small but critical part is strong and dimensionally accurate, inside and out. Exacting internal dimensions allow the smooth operation of both plungers, while extra-long staking studs provide plenty of material for a solid attachment to the frame that won’t work loose.
The Nighthawk Custom line of Fully Machined parts are designed to be the gold standard in the 1911 parts industry—all Fully Machined parts are fully CNC machined from solid steel billets, and Nighthawk never uses cast, metal injected moldings, or polymer parts. A 1911 plunger tube prevents the slide from locking open before the last round is spent and holds the thumb safety on until you switch it off to fire. Upgrade your 1911 with this premium, fully machined component engineered for reliable performance and durability.
