Well, after using the my new PSR-500 for about 1 1/2 weeks, I quickly came to the conclusion that the belt clip is definitely inferior and certainly the worst part of this otherwise great radio. I dug around in the parts bin at the house and found a new Motorola HT1250 clip. It has a similar mounting style as the stock clip but it wouldn't fit without some modification. I cut the metal mounting part of the clip down using a dremel tool so it is roughly the same size as the "pocket" on the back of the radio case. I then removed the back of the radio's housing and slid the clip mount down on to the radio to check the fit. All looked good so I drilled 2 small holes through the back of the scanner case into the clip's metal mounting bracket to secure it to the radio and avoid a possible drop later. Everything snugged up well and then I installed the clip to the bracket using the metal pin. Screwed the case back on the radio and voila!.. a belt clip that actually works!
Mod was not real difficult but I would not recommend to anyone who is not comfortable taking apart and drilling through the case (not replaceable as of yet) of a $500+ radio. I've been a radio hobbyist for 20years and have modified many radios so I was comfortable undertaking this fairly basic, but easily screwed up project. I have included some photos of the mod for reference.
