I have just bought a S&W 626 7-shot 4inch revolver and am waiting for California 10 day waiting period. I know this might be a dumb question, but I have never owned a firearm before. I have heard people follow certain schedule when they "break in" their guns. Such as firing so many rounds, then cleaning a gun, firing more and then cleaning more, etc. And "so many" is just a few, like five or ten. Is there any reason to do that? Or should I just start shooting as I normally would and clean the gun regularily?
