I have some older guns, or otherwise collectible that it breaks my heart when I ding them. But, these rarely get out of the house much anyway. On hunting guns, I grumble then move on.
You are going to think this is BS but it is the truth.
I was pheasant hunting with about 20 other guys in northern Kansas near the Nebraska border. One of the guys grabs a brand new shotgun from the box. Walks over to a barb wire fence and proceeds to run the wooden stock on it. He loads it, shoots a mag full and then turns around. He walks back smiling ear to ear. His response? Now I can hunt with the damn thing and not miss birds because I am babying it. But, in his defense, it was a base model 870 so who cares. LOL
On the other hand, I had a Ruger .44 mag carbine. The gun isn't exactly expensive, probably ~850. But, it was a first year gun and though not mint, it was very nice, especially the stock. It had a forearm barrel band. In the past, if I had left the stock off guns with the barrel band, they have shrunk and I couldn't get the barrel back in. So, I slid a socket that was nice and tight in there. A couple weeks passed and I go to put it back together. My hands slip momentarily; just long enough to move forward and hit socket with enough force to act as a splitting wedge as it cracked the stock from there to the tip. My stomach literally felt sick for several hours. Nothing like damaging an otherwise very nice 60 year old gun.
