I use them on the magnum handguns. Just enough cushion, to make it more comfortable and improve the grip. I mostly use a pair of No-finger batting gloves. ...
During our M/L classes, in hot weather, I use them, on the loading bench so I can maintain a grip. During our live firing portion, I do all the loading and things can get fairly messy sweaty while handling bore-butter, lubed patches, RB's and rods as well as the M/Ls. They also afford, some physical protection.
Be Safe !!!
