I have a dozen or so of the props. They are all fully duel capable and have bright LEDs for cool color. A couple even have sound. GTH, a Jedi would either would either yank that .45 from your hand with the force (Vader in Empire Strikes Back, perhaps?), hack off your hand before you knew what was up, or deflect your shots with his or her saber. If you kids at home want to try deflection, get a lightsaber and a nerf gun. That's some serious fun.
UPDATE: Oh yeah. I've won 150 lightsaber duels in my backyard according to the rules set in place by The Lightsaber Duelists of Phoenix. (that's my group)
UPDATE: Yeah, I'm back. Go here and you can rate my sabers...
