I have one that belonged to my grandfather and was passed to me. I don;t think it had ever been cleaned prior to me getting despite the fact it had probably been fired 50000 times
I’ve given it two thorough cleanings in the last 30 years and it has ridden in trunks, gun racks, and behind truck seats for all those years and I may have had 3 malfunctions out of 20-300 shots.
If I had to walk away into the wilderness with one gun it would likely be this one.
