I do shoot the can wet. I only use water. Should I just quit being so OCD about it and just shoot it dirty until I get it jailbroken in the future?
Why are you so worried about cleaning it? 9mm does not lead up a silencer like .22 does. I've had my sealed .22 silencer for 3 years and shot well over 20,000 rounds. There is no difference in sound between it and my serviceable .22 Sparrow.. Just shoot the damn thing.
