So sometimes you buy things and they are pretty good, maybe even meet your expectations, but then there are times like this when all expectations are completely blown out of the water. I honestly did not know what to expect when I got the True Precision non threaded barrel for my Shield 9mm. Went to the gun range that following weekend and was shocked at how well the precision barrel functioned. The fit, feel, and accuracy of the barrel was flawless. I typically am not one for writing reviews, because I think it is important for people to formulate their own opinions without any kind of influence, but in this case I made an exception. Anyone thinking about getting a True-Precision barrel should "pull-the-trigger" because I can tell you that you will not be disappointed.
