I was talking to a friend at STI and it's not that small a percentage of revenue. It's going to cost STI a lot of $$$, but you need to go to their website and read the news blurb about it. They simply said enough is enough. From microstamping, where does it go from there? My hat's off to STI, and I'm a customer now. They are one of the few companies that have refuse to butcher up a well designed weapon to make the legal maggots happy, and because of that, I'll support them anyway I can and that includes buying their product.Makes sense. Why should a custom gun mfg try to comply with a ridiculous law for what probably represents a small percentage of their business?
