Feast your eyes on my late '70s Colt Combat Commander in .38 Super. I just bought it from a co-worker, who bought is 2nd hand in about 1979. It's only had about 250-300 rounds through it. I intended to change that! I got all that is pictured (Bianchi holster and double mag pouch, some ammo, bunch of brass, two extra mags) for the tidy sum of $400. My co-worker paid $350 back in 1979. Hard to tell from my Fisher Price digital camera, but it's about 97-98%, with just a touch of wear on the muzzle from going in and out of the holster. He shoots...he scores!
Those are Nill grips, one pair is stipled, one is smooth. I also have a smooth pair fair L frames. The grips on the 681PC are also Nill, but a different model.
