I also love how so many firearms have such low round counts! If you believe all of those posts, you would think that nobody shoots their guns anymore, and we have a bunch of Safe Queens just sitting out there waiting to be grabbed up by the *real* shooters!
Another of my favorites that is overused:
When asked about round count: "I'm not sure, I bought this used, and then *RIGHT AFTER* I bought it, I decided to buy XYZ, and didn't need it any more. It has been sitting in my safe for 2 years un-fired, and needs to find a good home. Perfect Condition..."
Gotta say I have a lot of guns with very low round counts during my ownership (some new/some used) and a few regular shooters that have tons and tons of rounds through them.
