I have been happy with my Mossberg 500 since about 1995; somebody else had it before then and sold it (after putting some serious miles on it). It came with a fixed choke 28" barrel for hunting, which i did. I usually keep the more recently aquired 18.5" cylinder bore (open choke) barrel on it now for home defense. I also swapped out some black plastic furniture (went with a full buttstock with pistol grip) for the worn wooden furniture and added a sidesaddle shell holder for an extra six shells on hand. It is the firearm i am most familiar with and would be the first i would grab if awakened; i figure it would get me to the safe and the SKS & pistols (and something bullet-resistant to use as cover).
If i feel the urge to kill some birds or an up-close swamp donkey, it takes about a minute to change the barrel and another thirty seconds to put a pencil in the ammo tube to "plug" it down to bird-legal capacity.
Don't have any good pics.
Old ass shotgun + ammo on the way to go dove hunting, $100; still having it many years and many, many rounds later in great running condition, priceless to me.
edit* I later ditched that stupid sling. I don't need anything getting hung-up and making a racket in a serious situation.
