Most modifications I've seen online recently have to do with adding lights to the WiiMote or painting your Wii console. While those are all respectable and entertaining mods, none may be quite as "real" as this Wii Metal Pistol Controller modification made out of 1/2 in think aluminum...

Some words from the creator, Flame500...
Ever since I heard about the Wiimote's camera based aiming system I thought "wow that would make an epic pistol" and since it came out I had not seen anything that looked like it could still stand up to the abuse of playing and also looked like a convincing pistol.
I believe anyone could build this mod given some decent tools and softer/thinner aluminum. The aluminum I had wasn't really ideal as it was made to be machined and thus was extremely hard. This made cutting it on my cheap as hell bandsaw rather tedious.

Or as Gizmodo put it, "The Wiimote is alright and everything, but what good is all the motion control in the world if you can't pistol-whip player 2? This Colt .45 Wiimote mod doesn't make the Wiimote fire bullets, but with this much "gunmetal" aluminum plate, the police will goomba-stomp your ass before you can say "Duck Hunt" anyway."
