While the S&W J-frame snub nose revolver is often hailed as a great pocket pistol, I've found that great pocket holsters for the J-frame can be difficult to find. The J-frame is already on the big size for pocket carry and many of the holsters out there are unnecessarily large, bulky, or push the butt of the revolver up and out of the pocket. If the holster prevents the gun from being carried comfortably and concealed, then what's the point?

If you're looking for a pocket holster for a J-frame or other similar snubbie, this gets the nod from me.
