I just ordered a Storm Lake 9mm barrel for my G27. It's extended and threaded with the threadsaver included. I'm looking forward to some less-expensive shooting on the range. Does anyone have any experience with Storm Lake? Any comments with regard to reliability or quality? I researched as much as I could, and it seems like Storm Lake and Lone Wolf are similar in quality. Are there any negatives to using an aftermarket barrel in my G27?
