With a warning - True Precision M/P Shield 9mm Luger Threaded Pistol Barrel

I gave 2 stars it would have been 3 but it costs me 140.00 dollars to fit the barrel to my handgun. It was not a drop in for my sw&mp sheild, it needed modifications and a chamber cover. The Smith test fired the handgun after the work performed.I would have been better off buying a new handgun that came with the threaded barrel, I would have had Smith wesson life time warranty. Now I probably don't have this warranty which I have to live with. My mistake I should listened to my gunsmith.
