I would HIGHLY recommend this holster from Bullard Leather; it holds the weapon very close. I have a K&D defender OWB and although it's a really nice holster, I find that you have to cinch it down a lot tighter to get it as close as the Bullard holster. I feel the Bullard Leather conceals much better than the K&D defender. I also have the SP101 with the 3". I also have a
Gun Leather, Concealment and Cowboy holsters, Azle, TX.
I also have this IWB holster on order so I can't comment on it but I think it'll be a good IWB for the longer SP101 because it has an adjustable cant for the revolver version. I post when I get it!:
