20 inch round barrel with full mag. chambered in 38 WCF caliber. There is still traces of nickel but most has turned an antique plum/brown color. Has a VG+ bore. Bright shiny with good rifling. A couple of very light pitting spots towards the muzzle and a very slight amount of scattered roughness. Generally you don’t find these bores nearly this good. A decent old Colt with an antique look to it.
