Very comfortable, well made, and makes concealment surprisingly easy. - DeSantis Thumb Break Scabbard Belt Holsters

I know leather, OWB, pancake holsters are old school, especially when paired with "ancient" guns like the Beretta M9. That said, this is the perfect holster for that venerable pistol. The organic, rounded edges of the leather, plus the tendency of a pancake holster to conform to your body makes it surprisingly easy to conceal such a large pistol as the M9 under a sweatshirt or light jacket. It keeps the grip tucked in nicely, so there's no printing or weird points or bulges sticking out. It supports the weight of the gun very well and is comfortable to wear all day long. Build quality is top notch, as you would expect from DeSantis. Being leather, it does audibly creak a little when new, but should get better when worn more.
