I bought a NIB 9mm P9S a few months ago and it's been sitting in the safe ever since. I bought it just to re-sell it at a later date...I had no particular interest in the model or caliber. I took it out tonight to oil it and I noticed that it's not a 9mm...it's a 45 ACP. It took me a minute to digest that fact. I bought it thinking it was a 9mm...but the mags, the box, the original factory target...are all marked 45. It was a nice surprise...now I want to keep it!
