I'm planning on getting a Rem 870 SG for duty use and home security. I can get a 7 shot 870HD (#5077) for about $300, or an 870P (#4901) for about $400. While $ is not a huge issue, is it worth the extra $100 for the 870P? Both come with bead sights, so maybe I could put the extra $100 towards some decent sights. BTW, I've had several 870 Wingmasters's in the past, and reliability / durability has never been an issue. Also, is the Benelli Nova worth looking at? Benelli has a great reputation in the LE world, but I can't seem to get past the plastic (albiet metal reinforced) reciever.
