Anybody use one of these.  The only down fall I have with it is that it only fits a 1.25 wide belt.  All my belts are 1.5 and I am pretty attached to them.  

Any suggestions on a IWB tuckable?

Milt Sparks VMII w/ the tuckable clips.  Had a SkyOps, but didn't care for it as it bunched up my pants a lot.

I have a Sky Ops for my P229. It takes a bit to get used to.  

I have a SkyOps for my full size Kimber and like it.  You do need a good belt, though.

I have a SkyOps for my Sig P220; aside from the belt size limitation you mentioned (I, too, much prefer my 1.5 inch belt), I find the space which hooks over the pant much too narrow; I wear jeans most of the time, and the leather label on the back of the jeans (right where I like to put my holster) does not fit the pant hook...

... having said that, with dress pants (or pants which the holster otherwise fits), it works well.
