Not the first handgun i had... but the first one I bought.
I was passing through a local/range gunshop one day and saw a nifty looking Colt New Service Army model in the case, asking price was $275, I asked if I could have a look. (this was in 91 or so) When I asked for a bore lite the sales man said, well when you come back with money, I'll give you a bore light. I showed up the next day with cash in hand, partly just to spite the guy.. but true to his word he threw in the borelight for free, along with a dozen full moon clips and the loading tool.
Its an honest to goodness WW1 gun marked US Property and all, it was re-blued in the 50's but the markings are still crisp and it shoots like a dream. These are going for A LOT more than I paid for it, and I'm very happy with the gun.
I've bought a few more here and there, but nothing was quite as satisfying as buying that Colt.
