I have certain guns that never see a factory load. I carry them around the farm, hunting, or occasionally when I run into town for few minutes. I've never fretted about it and I worry even less because of recent changes in MO's self defense statutes. Others will disagree and that's fine.
“Nine-tenths of tactics are certain, and taught in books: but the irrational tenth is like the kingfisher flashing across the pool, and that is the test of generals. It can only be ensured by instinct, sharpened by thought practicing the stroke so often that at the crisis it is as natural as a reflex.” ~ T. E. Lawrence
