DIY Concealed Arm Holster

Trace the outline of the gun onto paper. Measure out one inch from the outline at several spots and connect the points to make a matching larger outline of the gun. Cut out the template, using scissors. This outside line is the guide for cutting out the leather.

Trace the template over the leather piece. Flip the template over, place it on a separate section of the leather and trace the template to create the holster's back piece. Once the outlines are complete, cut the leather along each outline, using a utility knife.

Place the top edge of the back piece on top of the leather belt and use an awl and hammer to punch stitching holes where the holster is to be sewn to the belt.

Squeeze a bead of liquid cement along the top, backside of the back piece and press it to the belt. Sew the back piece to the leather belt, using the stitching holes and waxed nylon thread.

Place the top leather piece over the back piece and punch stitching holes along the outside edge of the two pieces, about 1/4 of an inch from the edge. Separate the two pieces and squeeze a line of liquid cement along the back piece's stitching holes. Press the two pieces together again and sew through the stitching holes with the waxed nylon thread. Tie a knot at the end of the stitching to keep the stitching from backing out.

Dip the entire holster, but not the belt, into room-temperature water for ten minutes. Then dip the holster into 180-degree water until it darkens -- approximately one minute. While the leather is soaking, wrap the gun tightly with plastic kitchen wrap to protect it from water damage. Remove the holster from the hot water, slide the protected gun into it and allow the leather to dry for 24 hours. Remove the gun, unwrap the plastic and slide the gun into the holster, which is now permanently molded into the gun's shape.
