Projekt : that would be the law enforcement model with the handcuff key lock out conversion... i have the same lockout.
the lil pin on the backside of the key is for the handcuff double lock.. i.e. you lock the cuffs so they wont come off "1st"lock then lock the secondary so that the cuffs wont get any tighter "2nd" lock..
