I have one of these for a 1911. Great holster if you like that type of retention. I would use mine more if I had a full size 1911 but that is a differnt thread.
I am sure the OP will come along soone with your answer but I would venture to guess YES. The holster retention is at the trigger gaurd and that is the same for all 9mm's. Looking at the pic, it looks like a 17 would hang out the bottom. (could be wrong).
