The new Muzzle Pad from Dark Star Gear is soft wedge for use with kydex holsters. It is designed to aid in comfort by cushioned the lower edges of the holster that can dig into the wearer and concealment by pushing the grip of the handgun into the wearer.
Soft wedges are not new. There are number of ways to improvise them and there are other purpose built wedges available. The ergonomic tear drop shape of the muzzle pad and availability of two different firmness levels makes the Muzzle Pad unique.
