One suppressor covering a whole safe full of pistols is the big draw of the Banish 45, and interchangeable pistons like this one are how it pulls that off. This M16x1 LH piston threads into the rear of your Banish 45 or Banish 46 and mates the can to barrels cut with metric 16×1 left hand threads. That pattern shows up most often on HK's suppressor-ready .45s, think USP45 Tactical, USP45 Compact Tactical, HK45 Tactical, and HK45 Compact Tactical, plus some factory threaded Glock 21 barrels. If your host wears one of those barrels, this is the piston that gets you connected.
Banish machines these from heat treated steel, which matters on a part that takes a beating every time the action cycles. The piston rides inside the booster assembly and lets the barrel unlock and tilt the way it needs to for reliable semi-auto function on recoil-operated pistols. Each one is engraved with the thread diameter, pitch, and rotation direction, so there's no squinting at threads or guessing which piston you grabbed out of the range bag. The left hand marking is a nice touch too, since it reminds you the piston tightens the opposite way you'd expect.
Changing pistons takes just a minute or two. Unscrew the piston from the rear of the suppressor, thread this one in, and you're set for your metric left-hand host. That quick-change setup is what lets a single Banish 45 or 46 jump from a rimfire plinker to a 9mm carry gun to a full-size .45 without buying a separate can for each. If you run HK hardware, this is one of those pistons worth keeping on hand permanently. Just double check your barrel's thread spec before ordering, since HK also uses M16x1 right hand on the Mark 23, and that one calls for a different piston.
This piston matches barrels threaded metric 16×1 with left hand threads. That includes the HK USP45 Tactical, USP45 Compact Tactical, HK45 Tactical, and HK45 Compact Tactical, along with some factory threaded Glock 21 barrels. If you can measure roughly 15.7 to 15.9mm across the threads and they tighten counterclockwise, you're in the right spot.
No, and it's a common mix-up. The Mark 23 uses M16x1 right hand threads, while this piston is cut left hand. Same diameter and pitch, opposite rotation, so you'd want the M16x1 RH piston for that gun instead.
Nope, this drops right into the existing booster assembly at the rear of your Banish 45 or 46. Just unscrew your current piston, thread this one in, and mount up. If you're attaching the can to a fixed barrel host like a pistol caliber carbine, you'd add a fixed barrel spacer, but for tilting-barrel pistols the piston alone does the job.
Most centerfire pistols use a tilting barrel design, and hanging suppressor weight on the muzzle can keep the barrel from unlocking properly. The piston is the heart of the booster system, letting the can's weight decouple from the barrel for a split second during cycling so the pistol runs reliably. Swappable thread patterns are the bonus, letting one Banish can serve hosts with different barrel threads.
