My guns fall into Category A and B. They are tools, but i'm fairly pissed if i damage or scratch them.
No harm to with being proud about your firearms, regardless of cost. Doesn't mean i shy away from any work that needs done or taking tools to them, but from my little CZ to the most expensive one i have, they are cleaned, minded and stored carefully and treated the same when i'm out.
To me it's like a car. It's a toll to get me from point A to point B, but if it gets scratched i get pissed.
