The gun mentioned by PA24, the very low mileage Sauer on GB for $700 buy it now price, is one of the guns imported by my friend Ken Buch at kebcollc.com The seller is able to sell this gun for that price after giving Ken a fair markup. I've bought guns from both of those guys and the better ones are wonderful and underpriced. I bought a very lightly used Husky top lever hammer gun, fluid steel, from Ken for a ridiculously low price. He often has such guns, but, unfortunately, he doesn't seem to put them on his site. He has dozens more guns in stock than are listed on his site. Call him. You have to contact him for availability. PA24 picked a good gun to compare with the gun in the original post, which was no bargain at half the price.
