If it’s just like the K-Comp, it is not the Super K. It’s the Pre-lock F-Comp.
I won one on GB around a year ago in very good condition, for $1,200 no box/paperwork, original grips. Unfortunately the seller (Fugate Firearms) realized it sold for far less then they wanted and refused to ship me the gun or let me pay for it. They used the excuse I was in CA as a reason to not sell me the firearm, even though it’s perfectly legal for me to own the gun, and them to ship it to my FFL. When I tried talking to them over the phone, they resorted to vulgarity and cussed me out. They refused to talk to my FFL, even though I provided his number. They also didn’t have any posting on the listing they wouldn’t ship to CA. Very dishonest, and downright rude people.
Anyways, $1,200-$1,800 would be an acceptable price to pay for a pre-lock F-Comp.
