The major leather cutters have been very slow gearing up for the 3" and 5" guns but there are some options.
Galco's Miami Classic II (see avatar) is a good carry for the SubCompact and is available in black or tan for righties but just tan for lefties.
Otherwise, Galco's Silhouette is a good ride for a SubCompact as it rides high and tight and is quite comfortable. It is an open muzzle "slide" type holster but the muzzle of the 3" gun just barely protrudes.
The picture below really doesn't do it justice.
The SkyOps tuckable IWB for the 4" Service guns will work with the SubCompact but you will have a little bit of empty space near the muzzle.
