You may get 20 different answers but this is what I do. I take a new gun home and clean it the same way I clean all of my handguns and take it to the range and put 500 to 1000 rounds the first time I shoot it. Take it home and clean it again. It should not hurt any new gun to put all the rounds through it you want the first time or two you shoot it. I know some guys that shoot several thousand rounds without cleaning a new gun just to see how many rounds you can put through it before it malfunctions from being dirty.
