A M27-2 from late 60's (P&R), with the 3-1/2" barrel is on my short list. I have a very nice M28-2 with a 6" barrel, so I want something shorter in a M27.

What's the going rate for a blued one? Don't need the box, target stocks nice but not necessary, but better than average condition. An "S" prefix would be a real plus. (and plus more money, I'm sure)
