I've been doing a good bit of research on the .500 Linebaugh Maximum and pretty much from what I find it is about even with the 500 S&W. What the 500 Linebaugh Max seems to offer is that you can pack it easier, it doesnt weigh 72oz or have an 8 3/8" barrel. Dont get me wrong, I still like the idea of a 500 Max and that its different, not alot of people have one...I will have one as well as a 500S&W
By the way, I must say it is refreshing to find others like me who dont get these big bore revolvers because we want to look tough, we get them because we like them.
