I have an old police refit M&P 45 kicking around here somewhere, early model that won't take the Apex triggers due to a pin size problem. There are other things that can and have been be done though to make it better. Wife has a .40 from her late father, and a later .45 racegun with a deltapoint sight and Apex target trigger that we both hate. Lot of money there and it's more of an heirloom than anything. The .40 can rot, snappy and harsh to shoot, bulky and thick, the M&P autos are reliable but I would never spend money on another. I love my slim, graceful, well-mannered 1911s. Never got into the Hi Powers because there is nothing a 9mm can do for me that a .45 ACP doesn't do better.
