Okay, here's how I thought it was:
The Mossberg 590 is an 8+1 model with a 20" barrel.
The M590A1 was the same as above, but with a heavier barrel (preventing installation of a heat shield), metal trigger guard, metal safety, and the bayonet lug.
But I've read posts where people have been complaining about the plastic trigger groups on their 590s that have bayo lugs.
Can you put a heat shield on the heavier barrel? If not Mossberg factory, what about aftermarket? Will that Tac-Star shield fit? Can the Mossy one be modified?
Which versions do or don't have the bayo lug?
Just wondering. Mossberg only lists two 590A1 models on their webpage.
