Pocket holsters are an extremely easy home project.
Suggested materials are some felt fabric and button thread. Decide on 2- or 3-layer thickness. Wrap the gun as you see fit, staple to hold, stitch to fit. Trim and whip-stitch if you prefer.
Felt material is great, since it resists movement in pocket and exhibits very low friction against metal.
Cheap and inexpensive. Holster wear negligible. An evening project while watching TV.
