The Yankee Hill Machine Nielsen Piston (brand part no. YHM-2062-24) is threaded 9/16×24 for 10mm-class pistols. It’s compatible with YHM’s booster housing (YHM-2055) as well as many other popular pistol suppressors, letting the barrel move independently of the can under recoil so a recoil-operated pistol’s slide gets the momentum it needs to cycle.
