The Q Boombox 8.6 Blackout pistol (Q part no. BOOMBOX8612INPISTOL) stretches the platform out with a 12-inch barrel while keeping the brace-equipped pistol configuration. Q LLC built the Boombox around the 8.6 Blackout cartridge, a round designed for short barrels and suppressors. A 1:3 twist rate stabilizes heavy subsonic bullets, and an adjustable gas system lets you tune the gun for different loads. The longer barrel gives a little more velocity and a more balanced feel than the 8-inch version, without moving to a stocked build. It is a compact, suppressor-first pistol for shooters who want heavy-bullet performance in a small package.
