Abstract: A holster having a reinforced front portion to prevent the holster from collapsing under pressure from the wearer's belt when the gun is drawn. The holster is preferably made from rigid leather, molded to conform to the specific gun intended to be carried. A rigid leather reinforcement, which may also include a metal or plastic plate, along only the front portion of the holster is sufficient to keep the holster open when the gun is drawn, without increasing the thickness of the holster, thereby maintaining concealability. This reinforcement is particularly desirable for inside waistband holsters. Such an inside waistband holster may have a single central or rearward belt loop, or a pair of belt loops, with one mounted in front and the other at the rear. The belt loops may be reversible for weak side wear. Additionally, the reinforcement may be used with strong side or crossdraw belt holsters.
