how do you break in a pistol barrel?
I have read a bit about breaking in a rifle barrel, but very little about pistol barrels.
Many seem to advocate that rifles are cleaned after every round for the first 10-12 rounds followed by cleaning after every 5 shots until you have fired at least 30-40 bullets through the rifle...or at least until the copper residue stops being deposited inside the barrel.
What is your opinion on breaking in a rifle barrel...and also, would you perform anything similar to this for a handgun?
Also, a friend just bouhgt a Beretta CX4 Carbine. He'll get it in about 2 weeks...and he was concerned with breaking it in right. Would you consider the Beretta 9mm CX4 to be a rifle, or a LARGE handgun? How would you break that gun in?
