Incorrect listing information! - Jacob Grey Firearms 9mm Luger Barrel

Turns out this is a nice barrel but the listing has wrong information! The correct thread pitch is 1/2 X 36"NOT 1/2 X 28" which is what the listing describes. I bought this barrel and a Kaw Valley slim XL compensator in 1/2 X 28" and I destroyed the compensator because it cross threaded! Very disturbing. I took it to my gunsmith who had to cut the compensator off and luckily saved the barrel because it is steel and the compensator is aluminum and it shredded the threads in the compensator. I alerted Optics Planet lets hope they make this right! If you buy this barrel get a muzzle device with a 1/2 X 36 thread pitch not what the listing states and Optics Planet needs to update the information for this barrel!
