Not real familiar with this pistol...yet. Does it lack a slide stop mechanism? I'm cleaning one for a friend and it will not lock open with empty mag. There's nothing on the side of the frame I see either. Will be doing a fluff & buff this weekend, per the advise of the board 
Sorry for the Newbie question, but I could not find anything using a search. :-[
