The one i've got has 1/2x28 thread pitch. Running KX-5 on it at the moment.

Standard thread pitch for the barrel end is 5/8x24tpi, the use of a 1/2 x28tpi on a 9mm barrel is no good as the steel left surrounding the muzzle will be compromised and will eventually fail, the 1/2x28tpi thread is suited to the 5.56 calibre rifles and should not be used on a 9mm platform
cheers guys and good luck
