$1800 is neither rare nor expensive.
While its not rare, today, $1800 is still considered expensive by some of us. Especially those of us who don't make a lot of money.
The most expensive gun I ever bought was $1500, and it cost more than the car I was driving at the time. However, that was some time ago. (and that $1500 gun sells for nearly double what I paid, on today's market )
Ask yourself one question, IF that rare, expensive gun suffers damage from shooting it (or being handled) what do you actually lose??
And, remember to figure in that the value of a gun in dollars ONLY matters when buying or selling. If YOU are planning on selling it at some point, then damage will cost you potential value.
If you aren't, then what is the possible loss? Reduced (potential) value of your estate?? Is THAT a serious concern to you??
Do you think one of your heirs is going to say "gee I wish Dad hadn't shot that rare Luger, now its only worth $3000 instead of $4000!..."
And even if they did, what would that matter to you, then???
