My local gun pusher has been trying to sell me a Pre 27 in the attractive 3 1/2" barrel lenght. The gun has seen a good bit of use but looks good and locks up and times nicely. The magnas are very good. Unfortunately, the barrel has clearly been cut down (to my eye anyway) to 3 1/2. I am tempted to make an offer for the gun minus the barrel. I have a spare 27 barrel (6") laying around here somewhere. Any ideas as to a reasonable offer?
