I looked at the barrel in the thread. I bought my wife one of the Bodyguards with lasers when they first came out. Her barrel has the seam mark and is obviously MIM.
Mine has no marks like that. It has 380 on the top of the barrel and BG380 on the side. If it's MIM, then I'll have to live with it or sell it. That being said, I am not happy with a MIM barrel on a gun marked S&W. I have plenty of revolvers and most all have MIM parts, not the barrels. Even Taurus isn't using MIM barrels.
I know MIM has its cheerleaders. I am not one of them for the use on barrels or cylinders. MIM is purely a cost saving method for companies. What bothers me the most is I bough my son one of the guns when I bought mine.
