The "V" should be before the serial number.
If so, that would make it a "Victory" model M&P. Not particularly rare but a good shootin' iron. I'd suggest not shooting +P loads, but other than that, enjoy it!
My 81 year old mother still has Dad's Victory model M&P, loaded with 5 rounds of .38 Special 146gr LSWC-HPs at about 900 fps. Just enough to get the job done.
