I can't say anything about the Don Hume, but I absolutly love my supertuck. I understand not wanting a huge holster but that's what makes it so comfortable. I used to carry my g 23 in a Galco Summer Comfort. it was small and worked well. O have had my Crossbreed for about a month and I don't even notice it there. The huge back distributes the weight of the weapon across the whole holster. With my Galco I could always feel it. it was like it was always poking me and I was always adjusting it. With the Crossbreed, once I adjusted the cant to my liking I don't have to worry about it. I can feel a slight pressure but it's not at all uncomfortable. Also don't let price make the decision for you. If you plan on carrying everyday it should be about comfort, durrability and concealibility. I've had this conversation with a friend of mine at work and he's trying not to break the bank on holsters and wants to buy a cheaper priced holster. I told him that I started out the same way and now I have a few hundred bucks in holsters.
