You're all going to hate me, but...Holosun 509. Closed emitter and reticle options make it ideal for shotgun applications. While I think the Trijicon is often the logical choice as a red, meat-eating American, Holosun features are simply superior. If you're stuck on Trijicon, the best would be their RMR HD.
