Or stop worrying about it.Ok thanks. I did scrub with a bronze brush and Hoppes No. 9 - guess I just need to keep at it.
Thanks I feel better!When I worked in my unit's armsroom, (over 40 years ago), virtually all the raggedy, worn-out, old 1911A1s had that in their barrels. Since those pistols were over 35 years old by then, I figure that it hadn't hurt a doggoned thing. I haven't noticed any issues with it in my personal pistols, either.
