PTAC 2-in-1 IWB/OWB Pancake Holster - Right Hand
[PTAC 2-in-1 IWB/OBW Pancake]

I bought one of these for my Beretta PX4 to use as an outside the waistband holster. I found it is the most comfortable holster I've ever worn. It keeps the gun snug to your body making it barely visible even when wearing a T-shirt. I liked it so much I ordered one for my M&P Shield.
