A few weeks ago I received a JM Custom Kydex AIWB holster. Thus far it has carried exceptionally well and performed beyond hope. The gun as many on this forum will agree is a pig any way you slice it at roughly 38oz. unloaded. However, with a decent belt it carries just fine and conceals as well as anything else I run.
The design pictured below, if I can get pictures to load, is a newer design featuring a Raven Concealment Systems "Claw" which really helps tuck it to the body. Coupled with either the foam concealment wedge or the extra tuck option and the thing is a ghost on your waistline. The decocker functions while holstered and the holster itself can be molded to either the SP-01 or the Tcatical model. Just add the specifics in the notes.
