There’s a few fellows that wear shooting jackets offhand at Friendship, and I seem to recall seeing a glove or two, but don’t quote me on that. I rest my rifle with my fingers curled and the forestock sitting in the crook of my hand between my thumb and index finger right in front of the lock, so I guess you could say it’s really not in the palm, but I’ve never seen or heard anyone complain about how someone holds a rifle. And yes I’ve seen some who rest their entire upper arm and elbow against their body, but I’m old and can’t contort myself like that.
You’ll see about every imaginable way to hold a rifle there.
