Threaded barrel for full size Sig P220 .45 auto
I may have an opportunity to purchase a threaded barrel for my full size Sig P220 .45 auto from a good friend of mine. He does not know what to charge me for it, and I don't want to offer him too little.
The barrell is made by Jarvis and he has put less than a box of rounds through the barrel. He said he bought the barrel 1 1/2 years ago, but has no idea what he paid for it.
Any ideas of what I should offer him?
