Ha! I have no idea what the answer is to that, but the question tickles me...
Last night I was rummaging through a kitchen cabinet and on the very top shelf I found a large old plastic container (looks like something a bunch of cheese-balls or some kind of cocktail bar food mix cam in). In the container were five locks from various guns, two of which bear brand names - Colt, Mossberg - while the others don't. Also found a padlock with "Ruger" on it.
It got me to thinkin', "How much do they add to the price of the firearm to cover the cost of these locks?" Made me laugh. Especially when I consider how many more of them I have stowed away in original boxes/cases, etc.
My question is, what can I do with them, 'cause they AIN'T going on any of my guns?
