The Freedom Armory Machine Works Grenadier 45 is the company’s second suppressor design to utilize its Gas Indexing Technology, which allows the user to custom optimize the unit’s sound-reduction capabilities for each gun with which it is used. Different guns can generate different muzzle gas pressures using the same ammunition, and the GIT system allows the Grenadier 45’s baffle ports to be rotated so that they are aligned in a straight line for performance in high-pressure applications and then quickly rearranged into a spiral configuration that favors low-pressure use. The Grenadier 45 is a .45-cal. suppressor that provides up to 32 dBs of noise reduction, can handle up to the potent .458 SOCOM cartridge and is rated for full-automatic fire with .45 ACP and 9 mm Luger ammunition. Unlike many other designs, the Grenadier 45 allows for complete disassembly of all components, including the piston housing, without the need for special tools. All parts are titanium, with the exception of the stainless steel piston and piston spring. Price: $950.
