Nothing too special, I just got my belt clip for my P32 and I did a few quick searches to see what was needed to install this thing..
Simple is too complicated of a word for what is needed here.. ;)
I got the kit and started with it.. I think it took me less than 10 minutes to install and take pictures and I'm getting over elbow surgery on my right arm that makes it next to useless..
The kit.. A new rear pin, screw, allen key, belt clip and instructions..
Here are both the old and new pins. New pin is in the front.
This is what you're looking for. A centered pin with threads viewable.
I installed the screw and clip to make sure all was going to fit well, then removed it all and added some blue loctite to the screw.
All done.. Like I said, nothing too complicated, but I thought I'd just throw up a quick install doc.
