I'm a .45 Colt-family kind of guy - but I would still get a .45-70 instead of a .460 SW in a *rifle*. Nothing wrong with, but don't see the point in a rifle when .45-70 exists, due to the .45-70 being lower pressure, and the size of a rifle.
460 SW is the best carbine/pistol combo I have run across on paper.
Plenty of options out of a pistol and plenty of range out of a rifle. 200+ yards and probably could be stretched to 350+ in an emergency.
I could carry 45LC pistol ammo and 460 SW carbine loads, be able to easily see/feel which is which and still use both.
An interesting combo IMO.
It is pricey, but I am paring down my collection. My original "collection" phase has passed. It isn't like owning 5 different wood planes. Guns have a lot of overlap and spending more time with one generally nets me better results than having more than one to choose from. I can let a few things go and the price becomes more reasonable. Especially if the claim of being able to cycle all three rounds is true and the general function is there. When they posted they were engineering this rifle I assumed the shorter rounds would be manual feed non-repeating.
