i finally decided on the mossberg 500 shotgun (8 shot/20" barrel) with pistol grip and heat shield. its my first shotgun. looks identical to this one. i'm gonna buy it next weekend. comes to about $230. i think i'm gonna buy the following advanced technology parts: 1. top folding stock with pistol grip - $50 2. 5 shell holder - $13 3. light/laser mount (it mounts to the mag extension) - $9 heres a pic of said parts mounted plus some other stuff they offer. what do you guys think of the setup i want? missing anything?
