I have a Millennium pro .45 coming, as I sold my millennium .45 to get the pro with polished internals and have an all black gun. Both are 145's with the 10rd mag. Great gun for the money, after the first 100rds I never had a problem at all. You are not likely to find one in MA for reasons stated above, though they are nice opposed to what I have heard stated by others. I would opt for the 745 to carry, as the 145 is a little bulky, but not so bad it can't be concealed in a good holster. If you have the money, there are better guns out there, I won't tell you otherwise. The Millennium is built decent, just not the same as some higher end brands. It works well, though if I had the $$, I would have an XDm. I have a pic on my wall of an XDm that I dream of, but the funds just aren't there. AR will come before I upgrade.
I have no idea what is available in MA, but maybe look for an M&P? Even a Sigma, as I can imagine it's better than a Taurus. With the limitations in MA I wouldn't look for a Taurus, it's not something I would buy used.
