Longer review coming, but the short form is: the CABOholster works for me, and Lane is a pleasure to deal with. YMMV on the first -- different strokes, and all that -- but is vanishingly unlikely to vary on the second.

I had been looking at the Tucker Texas Heritage IWB, and some others. The CABO lineup looks intriguing as well. thanks for that link.
I would still like to find one where the inner leather piece goes high enough to completely cover the hammer. That is the only thing I have found uncomfortable with IWB revolver carry.

The thing that I really like about the CABO -- well, one of 'em -- is that it keeps the cylinder above the belt, yet is very stable. I don't have another IWB that does that.

Okay, yes, I see that now. That could make a big difference in the perceived (I think that term could apply in this case) thickness of the gun.
Have you received one or just ordered it? That design looks like it would bring the S&W 686 family, the Colt Pythons, Troopers, 67, etc. and similar sizes into serious play for carry. (IWB)
I still like the pocket snubbie for dropping into a pocket and heading out the door and the various autos all carry well with a good belt and holster, but dog-gone, those bigger revolvers are so comfortable in the hand and nice to shoot.

Keep us posted.
