A couple of comments from my observations and comments on a different forum.
AR platform guns are assembled by temporary workers, not permanent staff. The parts don't require fitting as did the older revolvers and semi autos.
The company that molds the M&P pistol frame is in CT, but owned by S&W. No word on whether that operation is going to be moved.
Revolvers are now longer built by "fitters" but are assembled via production line. Those who have bought revolvers lately seem to have a higher level of failures out of the box than in the old days.
S&W has over 100 CNC machines in Springfield. By a combination of moving newer and buying some new machines, they can move a lot of that to TN.
Houlton is not affected by the move,
Houlton factory unaffected by Smith & Wesson’s move to Tennessee
If you've ever seen the forge in Springfield, you know what a job it would be to move that. That and revolver assembly will only take up a small portion of the factory. I won't be surprised if that is moved sometime in the future.
Interestingly (to me), my son mentioned Knoxville as a place where my wife and I might want to relocate. Someone else mentioned Maryville and Alcoa. I wonder what real estate values are going to be like in a few months?
I wouldn't worry too much about people fleeing MA because their jobs moved (not a huge number) will do to the local politics.
I'll say this one last time. It's not the "outsiders" moving in to your state that are doing this. It's the public schools and libraries that you are funding with your tax dollars. Pay attention to those, not the license plates on your new neighbors cars.
Sorry for the thread drift, but I'm tired of the clueless blaming the change in demographics on outsiders.
