Here you go PigPen. I have one for my five-inch Model 27. Like any shoulder holster, they take a little adjusting to get right.

Oh yeah, the Cabo holsters mentioned above are nice but they're thick leather too. Much more so than the Sparks you already have. I don't think they'd work well under just a light T-shirt or whatever.
I'm firmly convinced that when it comes to holsters you never know what's going to work until you find the one that works for
you--your build and the way you dress. I've tried many difference brands and styles including the aforementioned Alessi and Sparks with no success (holster hunting can be expensive), but none works as good as the CABO for big revolvers
for me.
I definitely agree the CABO doesn't
look like it will work, and I was a little disappointed when I first opened the box, but what can I say, it works and works well for
me, and what I carry. After looking at it a while and wearing longer, I think it's success when it comes to me and my build is that you wear it considerably farther forward than most IWB holsters--basically the three o'clock position versus the four or five o'clock position with most IWBs, and thas position works best for me in terms of concealment and comfort (and the arms, when they are hanging down by your side also help the mask the weapon). Like anything else, YMMV.
I still part of the original poster's problem could be the 2.5" barrel length not giving the belt/trousers enough to work with for the weight/length of the weapon which causing it to cant out (again for experience and experimentation with carrying large revolvers). Another factor, and it wasn't specified, was the grips. The nice full-size rubber monogrips or combat grips that make for easy shooting generally make for poor concealment--a bad trade-off (shootability or concealability). Shorter wood (preferably smooth) grips generally aid concealability though rubber Hogue Bantums work well on my 3" RB K-frame (but it's not a 2.5" L-frame).
The bottom line, unless he is lucky (as some are), he's probably in for a long (and expensive) process of experimentation to find what works for him and his build.
