I've been eyeing them up myself, but the older JM ones. Like you, I don't need it, and if you expect anyone here to talk you out of it you've come to the wrong place. Even with a short barrel these are not exactly lightweight. However if you've had shoulder surgery, and I don't know your particular situation, I'm thinking a 45-70 is not the rifle for you, even ported. However if you check out the prices of the older JM models, roughly 2X for a good condition one, than what you're currently looking at, then price may have made the decision for you. Just a couple things to consider.......and no, I'm not trying to talk you out of it. I would never do such a thing at the risk of being banned by the gang here! Because as we all know "need" has nothing to do with rifles. Finally, you can always sell it later if it's not for you and chalk it up to experience.
