First I will say that the delivery time was faster than I expected. I received it in 10 days. To change the barrels was a breeze. I had bought my original Bond Arms with the 3″ 45 long colt barrel. It was an experience to shoot a high caliber round from a small barrel. It’s called a hand cannon for a reason! Buying and firing the 45 colt/410 was even more exciting. From 15′ I fully covered a 3’x2′ target with 2, 2 1/2 inch 6 shot 410 shells. You know that feeling you get, when you get something you really enjoy, and it makes you crack that smile? That is what happened with me! Great product. Great fun.
