Just take the firing pin and stroke it on a piece of emery cloth. Works wonders. and the breach face can be cleaned of microstamps the same way.
That's what they want you to do. They WANT as many legal gun owners to perform an illegal act.
The book "Atlas Shrugged" had a relevant passage:
“Did you really think we want those laws observed?” said Dr. Ferris. “We want them to be broken. You’d better get it straight that it’s not a bunch of boy scouts you’re up against... We’re after power and we mean it... There’s no way to rule innocent men. The only power any government has is the power to crack down on criminals. Well, when there aren’t enough criminals one makes them. One declares so many things to be a crime that it becomes impossible for men to live without breaking laws. Who wants a nation of law-abiding citizens? What’s there in that for anyone? But just pass the kind of laws that can neither be observed nor enforced or objectively interpreted – and you create a nation of law-breakers – and then you cash in on guilt. Now that’s the system, Mr. Reardon, that’s the game, and once you understand it, you’ll be much easier to deal with.”Once you've filed down the microstamping, all it takes is one surprise police inspection, either because of a "domestic violence" incident, or some other excuse for police to get a warrent to search your home for your guns. Then when they find that you've illegally filed off the microstamping, then they can arrest and jail you without having to prove anything further.Ayn Rand, ‘Atlas Shrugged’ 1957
