Milt Sparks Versamax 2, Watch Six, or Executive Companion:
http://miltsparks.com/IWB_holsters.htm. Versamax is a fantastic holster, but with the wide slide on the 92, I'd probably go with the Watch Six.
Rosen ARG (they have a cheaper version in their Express line):

Bulman Gunleather makes awesome holsters, I have several, but they are not taking orders now.
Garrity Triskel or Incgnito:

I have seen lots of folks getting excited about the Crossbreed, but they just don't appeal to me. This is no attack on Psa1m44, so don't take it that way.
I do carry a G22 concealed daily, and have carried a 92 concealed as well, and the 92 is harder to conceal due to the wider, longer slide, thicker all around grip, and grip shape.
I would suggest getting a holster where the mouth is only reinforced on one side, like Garrity's, or not at all, like the Watch 6, because the slide is just to darn wide, you'll want to minimize the holster thickness as much as possible.
There are so many great makers, but the ones I listed I know are taking orders right now, though Sparks only takes a limited number each month, but their October quota is still open.
