Picked up a MK 23 (1997) for a good deal. It has been fired 3 times, but by the looks of it you would say it was new. The owner had two and I asked if he mistakenly sent me the NIB one and he laughed and said "No, I put 3 rounds down that barrel, cleaned it and it's been sitting in the safe next to the other one since 1997". So now the question is, do I shoot it or keep it for the collection? How much will I kill the vaule if I shoot this thing?
