Have a few questions in regards to a model 27-2 Nickel finish, N serial prefix, I was told was available. Hoping to see soon, but from verbal description it has 5 3/4" barrel measured from insided frame (from front of cylinder) and has red ramp front sight. It is in a wooden presentation case with blue liner, with no indented slots for tools. I hope it has the small drawer access, but the case may not be original to gun. My questions are: Is it possible to have a factory 6" bbl that is actually 1/4" shorter? Also is it possible to have a factory red ramp front sight on a 27-2 other than the 4" bbl version? I am hoping to view in person soon, and have a better idea on true bbl. length and if the case is original, but wanted to gather any other opinions. Thank you for any replies.
