M590A1, 20"er. Didn't like the synthetic furniture (which the gun beat me up with) & snagged one of Havlin's last sets of the old style 500 wood sets. Promptly cut 1.5" off the stock & put on a Limbsaver & it couldn't fit or shoot better.
Stays stoked with Federal 00 "LE" with the Flite-control wads.
