Faxon 48 barrel - Faxon Firearms Duty Series Glock 48 9mm Luger Threaded Pistol Barrel

I was highly disappointed with this drop in barrel because I spent hours hand fitting it to my slide. This required a lot of removal of metal around the chamber area of the barrel. I have not been able to shoot it yet but really hated removing / filing off the protective black coating. I am a gunsmith and was able to do this, I don’t think the average person would have the skills to accomplish this.
