Hi, Hotchkiss! No, you probably won't see gloves used very often. But, at one of the more extreme 3 gun matches I've shot, the ITRC, we did use gloves. Because, after 300 rounds of handgun in under ten minutes, the pistols literally were to hot to touch. Doc's fiber optic front sight even melted on his STI, and the carbines got pretty warm too. But, normally, people won't use them. I don't think there are any rules against it, but dexterity is the big trade-off.
