Looking for info: found a S&W model 14-2 with a 5 inch barrel. Never seen one before, and didn’t even know they were made, but they are identified in the standard catalog of Smith and Wesson. Anyone out there know anything about this gun?
Are you measuring from cylinder face to end of the barrel?
If it is a true 5 inch there were several orders for law enforcement, Illinois State Police and Missouri Highway patrol. I think the LEO guns were before the 14-2 model change. There were model 14s with heavy barrels made for LEO but these were 4 inch barrels.
The only way to know for sure is request a letter from S&W Historical Foundation.
