Is this the holster you speak of?
If so, I guess it goes on the waist strap.
Actually piratelove asked but I was curious as well. I have the regular messenger bag (the larger one) and now you've answered the question.
Not my thing though -- my u-lock goes in my back pocket or the bag (usually the bag). I've used the waist strap as a rear lights holder -- I reversed belted it over the back of the bag. I'm not a big fan of waist straps, at least not for riding.
