The TecGrip Inside the Waistband (IWB) Holster is designed for both civilian and law enforcement concealed carry. The outer shell will hold fast to most any material, eliminating the need for a clip. Plus, a higher density, closed-cell foam design offers a comfortable wear and a snug fit. This holster is compatible with medium autos with 3-4" barrels and large autos with 3.25-3.75" barrels.
