I've got the Tucker Answer, and it works great, whether tucked or untucked. I carry a compact 1911 in it, but I think a full size 1911 or a Browning Hi-Power would work just as well. The Tucker is an exceptionally well-made holster and I recommend it without reservation.
It will certainly hold up to being carried empty, while you get used to it. The kydex holds its shape with no problems. That was one of the reasons I picked the Answer, because it doesn't require a reinforcing band about the lip to keep it from collapsing, so it can be thinner, yet still permit reholstering with one hand..
Here's the Answer and a Tucker IWB single mag pouch, also tuckable.
That said, I'm planning to carry my Hi-Power outside the waistband, in a "Regulator", by Nate at UBG Holsters. I've admired that particular holster since he showed the first prototype. I'd also like to have one of Eric Larsen's IWB rigs for it.
