Banish 45 — Multi‑Caliber Modular Suppressor with Quick‑Change Pistons

The Banish 45 is a modular, multi‑caliber suppressor built for versatility and real‑world use. Instead of swapping cans, simply change the threaded piston at the rear to match the host barrel—an easy, tool‑friendly method to move the suppressor between pistols and other firearms while preserving alignment and function. Pistons are machined from heat‑treated steel for durability and long life, and each is engraved with thread diameter, pitch and rotation direction (for left‑hand threads) so the correct piston is obvious at a glance.

Designed for frequent piston swaps, the Banish 45 accepts a wide range of factory pistol threads via purpose‑made pistons, letting one suppressor body cover multiple calibers and platforms. The robust construction and clear piston markings simplify logistics for shooters who run multiple hosts. Always confirm piston selection and visually inspect baffle alignment after changing hosts before firing.
