I've got a like new, Mesa Tactical SureShell for an 870. Holds 6 shells on the left side of the reciever. I don't like "Side Saddles" and thought maybe I'd like a higher quality one, but I like my guns slim and light. They sell for about $70 I think, I'd take $45obo. Comes with all hardwear and Allen wrenches. Possible trade for Beretta 92 mags, 00 buck or slugs, 9mm ammo and maybe other 870 stuff.
