sorry for all the posts but i am a rookie and love to learn. at first i did a B&F on my entire barrel, feedramp and it definitely helped feeds. but not 100% so i did the complete B&F. my question is when you did the B&F, should you reblue the bare steel inside the slide to prevent corrosion? does bluing even help with corrosion? or did you just keep it lubed and forget about it? thanks.
