Obviously, this is for FtF play.
I ran into these from a website off Serenity RPG.

The idea is to print off 2"x4" cards with all the necessary data to use a weapon (firearm or melee), which can of course include a keen picture of said boom-stick.
In a few Serenity sessions, the players all seemed to like them, as they could pick up or drop guns as necessary (the best reload...), and see more than a jumble of stats. The weapons guides or T2k2 have the necessary sections, one need only copy them from the book.
A downside, of course, is that now you have lots of small pieces of paper floating around.
Anyone else use something like these?
