The Bersa B45 is a high-performance modular suppressor engineered for the shooter who demands versatility, durability, and hearing-safe performance across multiple calibers and host platforms. Constructed from Grade 9 titanium, 17-4 PH stainless steel, and 7075-T6 aluminum with a High Temperature Cerakote finish, the B45 delivers up to 31 dB of sound reduction in full configuration, achieving approximately 125 dB SPL, well below the threshold for hearing-safe shooting.

The B45 is rated for 45 AUTO, 9MM Luger, .22 LR, .300 BLK subsonic, .300 BLK supersonic (hunting application only, 5 shots then allow to cool), 350 Legend, .357 Mag, and .38 SPL, making it one of the most caliber-versatile pistol suppressors available in its class.

A .578×28 direct thread mount is included, enabling reliable semi-automatic operation on most contemporary locked-breech host pistols right out of the box.

The B45‘s modular design allows users to configure the suppressor in seconds and without tools between the compact configuration at 6.9″ and 8 oz for reduced overall system length, or the full-size configuration at 9″ and 11 oz for maximum sound reduction delivering 31 dB suppression. The first five baffles are machined from 17-4 PH stainless steel, with the three front module baffles machined from 7075-T6 aluminum, fully user-serviceable and tool-free to disassemble.
