Re: Mossberg 500 or Mossberg 590...
I have both the 500 Persuader and the M590A1. You certainly arent going to loose anything in the 500 as an HD firearm. In fact, if you have the option to go with shorter and lighter for an HD gun, that would be my choice. Before you buy, ask yourself if the gun will be an HD only gun, or do you wanna use it for other things. If it isnt pulling double duty, you may want your HD gun to be light weight and easy to pull and maneuver when your half asleep. A light weight pistol grip can be far easier to pull from its resting place. just me sayin...
either one is a stand up firearm.
