Banish(Silencer Central) 4794 Pistons Banish 45/46 M13.5X1 Lh
$89.99
The Banish 45/46 piston is a replacement threaded insert for owners of Banish multi-caliber and modular suppressors who need to match different barrel threading on their host firearms. Instead of buying a separate suppressor for each gun, you can keep one Banish 45/46 can and swap pistons—giving you flexibility to run the same suppressor on pistols with different factory-threaded barrels. This M13.5×1 left-hand piston is designed for barrels threaded to that specific metric pitch and rotation, making suppressor ownership more practical and cost-effective for shooters with multiple platforms.
The piston itself is heat-treated steel, built tough enough to handle repeated installation cycles and the pressures of suppressed fire. Each piston is clearly engraved with its thread size, pitch, and rotation direction—so you'll always know which piston matches which barrel, even in the field or at the range. That attention to detail means less confusion and faster setup when you're switching the can between guns.
If you already own a Banish 45 or 46 suppressor and want to run it on another host firearm with M13.5×1 left-hand threads, this piston swap is far cheaper than buying a second suppressor. It's the kind of smart modular approach that works for shooters who refuse to be limited to one platform.

Frequently Asked Questions
Will this piston work with my Banish suppressor?
This piston is designed for Banish 45 and Banish 46 multi-caliber and modular suppressors. Check your suppressor model and confirm your host firearm has M13.5×1 left-hand threaded barrel before ordering.
What does M13.5×1 mean, and how do I know if my barrel matches?
M13.5×1 refers to a metric thread size—13.5 millimeters in diameter with a 1 millimeter pitch (distance between threads). The "LH" designation means the threads are left-hand, so they turn counterclockwise to install. Check your barrel specs or manual to confirm your firearm matches this threading.
Can I use this piston on multiple firearms?
Yes. As long as each firearm has an M13.5×1 left-hand threaded barrel, you can move this piston between them with your Banish 45/46 suppressor, letting you run one can on multiple hosts.
What's included?
The package contains one replacement piston with engraved thread markings for Banish 45/46 suppressors.
