The Bersa B9 Modular 9mm Suppressor is a pistol can built from Grade 9 titanium, 17-4 PH stainless steel and 7075-T6 aluminum (Bersa part no. BS-10002-F). It comes with a 1/2×28 piston, so it is ready for a locked-breech 9mm host out of the box. Without tools, the front module comes off to take it from an 8-inch, 11.3-ounce full-size setup down to a 5.8-inch, 9.2-ounce compact one. Bersa rates it for 9mm Luger, .22 LR, .357 Magnum, .38 Special, .350 Legend and .300 Blackout. It suits a shooter who wants a quiet 9mm carry or duty pistol and a rimfire host on the same can.

Key Specifications

• Bersa rates it for 9mm Luger, .357 Magnum and .38 Special, the handgun calibers most owners run suppressed.
• It is also rated for .22 LR, so a rimfire pistol or carbine can share the same can.
• For rifle cartridges, the rating covers .300 Blackout subsonic and .350 Legend, with supersonic .300 Blackout limited by Bersa to hunting use, five shots and then a cool-down.
• The mount is a 1/2×28 direct thread, the common pitch on threaded 9mm pistol barrels.
• A 1/2×28 piston is included, which Bersa says lets most contemporary locked-breech pistols cycle reliably with the can attached.
• Construction combines Grade 9 titanium, 17-4 PH stainless steel and 7075-T6 aluminum.
• The first five baffles are 17-4 PH stainless steel and the three front-module baffles are 7075-T6 aluminum, which puts the tougher metal at the blast end.
• The compact configuration is 5.8 inches and 9.2 ounces, the setup that keeps a suppressed pistol short.
• The full-size configuration is 8 inches and 11.3 ounces, which Bersa rates at up to 32 dB of reduction, about 124 dB SPL.
• The finish is black high-temperature Cerakote, and the can is tool-free and user-serviceable.
