The gun I was embarrassed to own was a Sig P228. For whatever reason, still unknown to me, I had left it on the passenger seat of my car. A synaptic misfire (aka brain fart). It blended into the black upholstery and escaped my attention.

When headed out for lunch, a buddy getting in the car noticed it and said "what's this?" I was embarrassed to own that gun because of my negligence and stupidity, not because the gun was embarrassing. I did learn a lesson that day.
