I just picked up a used M&P 45 ACP. Looking for more information, I know it is not a MOD 2 so I am thinking it is the predecessor to the Mod 2. It came with 3 mags, double stack and 4 inch barrel as I measured and has an ambidextrous thumb safety and the mag release can be comforted to left also. It also appears that is only 8 rounds as marked on the mags. I know it is not M2 as the slide is not stamped M2 and the grip texture is different for the M2 as posted on the S&W web site. I may have jumped a little quick not realizing that it was not a M2. Hope that was not a mistake. Any information is greatly appreacated.
