An earlier post had an issue about corrosion in the internal compensator ports of the new half lug Model 500.
I called S&W Customer Service this morning and got a guy who sounded like he knew his business.
He said corrosion wasn't an issue. He said that if one were concerned, to tilt the muzzle up and put solvent into the ports, let it sit for a while and then drain it out. He said that they haven't had corrosion issues with stainless two-piece barrels. Don
