I've sold 4 handguns in my life: a Taurus 445 .44 Special, Norinco 213 9mm, S&W M21-4 .44 Special, and Colt Cobra .38 Special. I sometimes miss the S&W and Colt a little, the Taurus and Norinco not so much. I've also sold three rifles: a No. 4 Mk. I Lee-Enfield, Yugoslavian M59/66 SKS, and a Luxembourg-contract FN-49 in 30-06, I regretted selling the Enfield almost from the moment I did but I don't really miss the SKS (too big and heavy for the cartridge) or the FN-49 (had issues).
