Are they addressing an issue that isn't there? At the height of my competition shooting I was running a thousand rounds of jacketed per weekend through my 1911, and I was running a thousand rounds of lead a weekend through my 2011. We are talking close to ten thousand rounds per year per gun. The only time I had issue with build up was/is in the compensator of the open gun. Once a year I take a tool and scrape the recesses clean. However, it has never built up to cause any issue with accuracy.
So, what is the issue we are trying to solve?
Is this a technology that works, but is more about marketing and "creating a need" that only Federal can fill?
