I just purchased a new M&P 9. I knew the trigger was going to be heavy because of the Massachusetts compliance rules but this is ridiculous. I shot 30 rounds so far. After doing some research I am told it will lighten up over time. I don't know for sure but it feels twice as heavy as some of my other pistols. Any thoughts on what I should do? Put a few hundred rounds threw it and reevaluate or do a trigger job? Is dry firing the gun with a snap cap the same as firing live ammo to break in the trigger? Thanks all.
