I know a lot of people shoot competition with pistols and shoot 100s of rounds. Will letting the barrel get too hot damage the accuracy? Is this more a concern with rifles? I have an aqautence with a full-auto AK and he takes breaks between mags. I was just thinking of this the other day when i put 50 rounds of .40 through my G20[with conversion barrel] and the slide was really hot on the front end. Would pouring water on it be a good thing?
