I've been carrying my P64 in this holster for the past 2 months now and have been very pleased with it. It was the thinnest holster I could find and the price was right at $25. It's a Galco made for a PPK and fits perfectly.
Here's the holster I made for mine.
Cost me whatever the belt clip cost, which wasn't much. I think Galco is a bit pricey on some items. Glad it works well for you.
