Lone wolf missed a little on qc on this one. - Lone Wolf Arms Glock 22/31 9mm Threaded Conversion Barrel, 1/2x28

Overall, I think this barrel is great. I have had a Lone Wolf 40 to 9 regular length barrel in my G22 for 6 years now. I wanted to invest in a suppressor this year, so I decided to get a threaded barrel. The barrel itself looks great and fit in the firearm no problem. The problem was the threaded area. When I took off the thread protector to install the barrel I could hear and feel the grit in the threads while removing the cap. I cleaned it off some and tried putting the cap back on. I didn't get far when I heard and felt the grit still. After a more thorough cleaning it was a lot better, but left me doubting Lone Wolf. I received a threaded barrel from a different manufacturer for my G30sf and the threaded area and cap came off and back on smooth as melted butter. I paid more, but I'm thinking it was definitely worth it.
