I would call Dawson, Thunder Mountain, and Brazos and ask them if they have had problems with any of them. These are pretty decent folks who move alot of STI's and who knows, maybe they could give you some feedback.I need some feedback about the LS 9mm as a carry piece. I've looked at it, but not fired it. Any experiences in shooting, maintaining this model? How is STI to work with when there are problems?
