Long, long ago, in a galaxy far away, a buddy of mine had a 3-inch 66, and I had a 3-inch 657. We shot them a lot, shot each other's, and shot them well. He didn't have much interest in getting my gun away from me, but I openly lusted for his. I eventually traded away the 657, but he kept the 66. Many years later, he still has that sweet little blaster, and I'm still trying to get it away from him. He steadfastly refuses to sell it, and I steadfastly continue to pester him. Maybe someday.
Enjoy those awesome little bullet launchers.
