The Colt Model 357 is not a Trooper.  It is Colt's original 357 premium holster revolver in the "I" frame.  The serial number is 123xx, and it was made in 1957.  This "pre-Python" revolver currently has a 7" aftermarket barrel installed that shoots 38 Special ammunition only.  The original 6" Model 357 factory barrel is included separately.  It would have to be installed in order to fire 357 mag ammo safely.  This revolver comes with a leather holster.  It also includes a box of 45 Speer once-fired 38 Special chrome cases, a full box of 50 Federal 38 Special 158 grain lead cartridges, and 2 full boxes (50 rounds each) of 158 gr. JHP 357 Magnum ammo from Black Hills and Garnet Ammunition.  Legal REDACTED 21 years old who reside in Montana can call four06273013seven for further infomation.  Reduced to $650.  Would consider a trade towards a Ruger SRH Alaskan in 480 Ruger.
