I have used them in the military and over seas but not for padding but because anything metal like your rifle you touch will burn you, also back in the states if it's snowing I'll wear some thin pilot gloves. In my personal life I have never had the need to wear them and I think it's kinda tacky like socks and sandals. I have yet to encounter a gun that recoils hard enough to even begin to warrant gloves. Then again I have not gone out of my way to shoot a S&W 500 because I don't feel the need to pay that much to shoot a silly round.

FL is the only state where you can buy any gun you want, but you can't shoot them.
