I don't know what cal. it is,but I think you have to use a rim fire after dark. I don't think center fire rifles are allowed. Check TWRA rules to be sure. I was wrong ONCE before. emoScratch
Picture not showing, assuming it's a pistol?? A buddy of mine used a Browning Buck Mark with a red dot scope, light in scope not laser, and loved it. He could walk em down on the dogs. Get a cross chest holster and would be a dream to carry.
