An appendix holster is a representation of how firearms ownership should be - accessible, comfortable, reliable and concealable when need be. The ShapeShift Ruger LC380 AIWB holster is made in America to respond to the concealed carrier's lifestyle. It's part of a modular holster system, which means the high-retention shell that encloses the sidearm's trigger guard and slide can be uninstalled from the AIWB holster backer and mounted to any of the available ShapeShift carry methods - like an OWB belt slide or an OWB paddle. The holster backer is designed to react to the concealed carrier's body. It has four layers of materials - a thermo elastomer front, an inner layer of ballistic nylon, a spring steel core and a rear layer of perforated neoprene. The thermo elastomer Alien Skin texture provides drag, durability and resilience. The ballistic nylon adds durability and strength. The flexible spring steel core molds to the body and provides structure to holster. The perforated neoprene ventilates the holster backer and wicks sweat from the body. The holster shell is made from an injection-molded polymer to fit the Ruger LC380 - as well as a select number of other handgun models, so multiple handguns can be swapped out with the ShapeShift system. An adjustable retention unit can be installed to control how tight or loose the retention of the holster is. This comfortable AIWB holster is made to withstand the test of time and adapt to the concealed carrier along the way.
