BUD'S GUNS has the M&P .40 1.0 unissued Detroit PD marked guns with night sights, 3 mags, palm swells, and a hard case. Does anyone here have one of these? If so, your opinion on it? And, when they state "unissued" is it still a new, unfired gun? Besides the night sights, has anything special been done to the gun for police use?
