Anyone know what a lightly used one is worth? When I first became interested in the 357 SIG cartridge I bought a G33/G27 KKM barrel for my G27 to try out the cartridge. After 200-300 rounds I bought a G32 and put the stock G27 barrel back in my G27 and hadnt used the KKM since. I just placed my G27 on consignment so I no longer need the KKM barrel. I would like to sell it but am not certain if there is any demand for used barrels. Any input or thoughts appreciated Thank You and Happy ThanksGiving!
