CONDITION: Overall very good, retaining the vast majority of the factory blue finish with some superficial handling marks throughout, some silvering. Thinning to sharp edges, particularly towards muzzle consistent with holster wear, and on dust cover, somewhat heavier. Typical silvering to reciprocating areas. Straps very good with some silvering handling marks and thinning, rear strap moreso to the bottom. Mechanically fine, bore with strong rifling and some light pitting towards chamber. A good example.
