After cleaning out my bore really thoroughly (it was as shiny and slick as a mirrored whistle, having killed a bronze brush in the process) I put my USP9 away, confident I would have no more rust/old primer gunk.
False hope, indeed.
Last night (about a week later) I put a patch through "just to see" and lo and behold, about 4-5 specks of nice bright red and muted brown flaky dust came out on the patch.
I didn't dry fire this time, so it's not like it could have been detached primer crud from the firing pin hole.
I called up H&K. The official word on rust?
"As long as it doesn't affect your performance/firing, don't worry about. Just keep it well cleaned after ever time you fire it, and that's all you need to worry about."
So.
Is that really true? On one hand, sure, I should expect a little more from my defensive handgun than that, but if it's just cosmetic and not exactly a problem -- I can afford to run a patch down the bore every other week to clean it out. If it really doesn't cause a problem, should I concern myself with it?
After all, if it's suppsoed to have passed all those crazy military tests, maybe they know that a little bit 'o rust ain't never hurt nobody?
What about leaving a coating of oil on the inside? I've heard that it's supposed to be catastrophic if you fire the gun without cleaning out the insides, and for a defense gun, I think that's asking a little too much ("Wait, please -- don't kill me yet. I have to wipe out my bore.")
Thanks again for all the help.
