The Glock 44 Threaded Barrel Kit (brand part no. 50480) is a factory replacement barrel built specifically for the Glock 44 in .22 LR, giving owners a right-hand-threaded path to run a suppressor on Glock’s rimfire pistol. The kit includes the M9x.75 RH threaded barrel itself, a .500-28 thread adapter, and a thread protector to keep the muzzle protected until a suppressor is mounted. It’s only compatible with the Glock 44 and is not interchangeable with other Glock models, even other .22 LR options. At 4.02 inches, the threaded barrel matches the G44’s factory-length dimension, so slide function and sight co-witness stay unaffected.
