How often should I clean and treat the bore for copper fouling, and what product do most shooters use?

Copper fouling is not something that normally happens at the lower velocities of handgun cartridges, so unless you are asking about your rifle, don't worry about it.

Thank you.
I never gave it much thought until someone asked me the same question.

It aso depends on what type of round you are shooting - i.e. hot 40's or a 10mm you might want to reconsider the frequency. Just my $0.02.
