I wanted as close to a real pistol as possible with the wii zapper. The Nintendo one just doesn't cut it. I made this in one hour from a cheap airsoft gun i had laying around. The grip safety works and the trigger pushes the wiimotes trigger (b button).
I skinned Chung Dha's paper wii gun template (chungdha.blogspot.com) with a glock skin making this the first ever barettaglockenspieler.

Step 1: Take apart airsoft gun
A lot of airsoft guns can be taken apart. This one was easily broken down. I can put it back together if I really want to later too!
