Defense or Sport?
If you are training with the pistol for LE/defensive purposes I would counsel against the routine wearing of gloves, especially those that are designed as "shooting gloves." For most of us it is unlikely that we will be wearing them when our gunfight boils up, so "crutches" are a bad idea. I do recommend that some training take place with them on so that if we are wearing them, like in winter, when Bad Things happens we will not be totally off our game.
I generally discourage the routine wearing of gloves by LEOs, except obviously when they are actually needed. Those are right up there with mirrored shades for presenting a negative image.
Now, after all that, I have the same problem. I usually use the waterproof rubbery high-powered bandaids over the web of my thumb. Moleskin, like you'd use on blisters also works well.
If you still want to use them, most of the Blackhawks are OK, Hatch may be better, and Ringers are super-duty, but you'd probably need to cut fingers away. Another option are the gloves designed for mechanics. I use some from Simpson racing that offer good protection and great dexterity. There is a motorsport glove maker that has started selling to the military that is highly thought of, but I have'nt tried their products and cannot remember their name.
IMHO/YMMV
