Well, I finally got to do some shooting today, and the gloves help a lot.
I can't say that my accuracy (offhand) is better or worse than without the gloves; it appeared the same, but the gun most certainly felt better in recoil, and I left (after shooting ~25 rounds of medium to hot loads) with no bruise on my support hand fingers like I normally get when shooting this one.
So far, so good.
