I found a MA compliant AUG09 M&Pc 9mm for $450 out the door (new)....but...the MA compliant scares me. They have a 10lb trigger rather than 6.5, 10rd mags instead of 12rd, and a trigger safety. Can the MA compliant gun utilize 12rd mags? Any other differences other than ones I have mentioned? I would have to have a gunsmith adjust my trigger back to 6.5 or down to 5lb...and buy all new mags....which would put the cost back to over $500. Watcha all think? I only own the M&P 9mm Pro - this would be my carry gun...nervous about that MA stuff!
