It has been mentioned, but tx custom dies has one that a lot of holster makers like. It's on my list of goodies to get. I have an osborn, but sadly it isnt very good quality and is also a bit narrow. For a 1.5" wide .25 thick belt, a 5/16 x 1.75 oblong punch is about perfect. I hand cut mine to this. I believe tx cust dies is about these dimensions also.
