Overcleaning?

[Bawanna]

I just function test after any cleaning or break down. I do the pencil drop, trigger reset, the whole smear, takes very little time.

I could see maybe a fouling shot on a sniper rifle but not on handguns.

Since this post, I've experimented a lot with how much to clean then how much to lube. Bottom line: the K40 is a brute and I can do whatever I darn well please. The MK9 is a little tighter and a little finickier. I can clean it as much as I want but it doesn't like too much lube. It's the only semi I own that doesn't get grease on the rails. Just my experience. YMMV. Maybe I'm foolish but I don't test fire before I carry. I've been thru enough to have confidence in both pistols.
