i just got the DeSantis mini scabbard for my M&P9c. it is a great holster.
the leather is thinner than the Galco Concealable, and it is considerably lighter. i dont really see the thin leather as being a problem with longevity or retention.
holster does not move around and sits comfortably strong side behind the hip.
the angle the gun sits at is not like the galco concealable... it is more verticle. so i wouldnt recommend this holster with a gun with a longer grip, as the grip will poke out of your shirt.
this holster is half the cost of the galco. wish i would have discovered this one before buying a couple galco's.
