I just picked up an M9A3. Beautiful pistol, with that Vertec grip reduction that makes it oh, so comfortable in the hand. Plus better sights (night tritium, drift-adjustable), trigger pull (lighter springs), finish, PVD mags, etc, etc. You pay a premium for the A3, but you definitely get what you pay for. My original M9 immediately went on consignment at the LGS (since sold) with zero regrets. The M9A3 might as well be an entirely new pistol - except that it's not. It is just a new, better sum of its improved parts.
