If I were you, I'd look for a used 870 or 1100/1187. I use my 1100 as my HD. Got a barrel from a guy here on the ODT for a great price and chopped it to 19in. Mounted an insanely bright light on it with pressure switch. I can dove hunt with the other barrel, and guard the hacienda with the other...lol
Total agreement here! Plus, you can add the Traclok ghost ring sight (Scattergun Tech) to the 1187, and 870. Aftermarket accessories are also readily available.
