Storm Lake Threaded Barrel

The threaded barrel offered by Storm Lake is not cheap, but not as bad as some others out there. The finish quality is very good, but a good polishing never hurt anyone. Initially there was no real issue with function, bAfter a little elbow grease and some fine grit polishing compound, the movement of the slide was noticeably smoother. Initial accuracy testing was conducted without a compensator or any spring changes, and produced about a 25% decrease in group sizes. At this point, I was able to pick off 18" targets out to 80 yards and 10" targets out to 50 yards without much trouble at all.

I believe there are other companies that make threaded M&P barrels, but as this is the only one I have significant experience with, I will not be comparing them here.
