Not to intentionally differ with the preceeding gentleman, but I have a SRH Alaskan in 44 mag and it is MUCH more compact than a full length barrel model. I bought mine with the same intention as you, more portable carry than a full size with 44 spl capabilities. You will have no problems with shooting 44 spl in it and then going to 44 mag unless you shoot several hundred rear dirty 44 spl out of it with lead bullets and then don't clean the chambers after. (no more problems than those that shoot 38 spl in their SP 101 and then go back to 357 mag; none) I do not plan to carry it concealed as it is quite big, but if a jacket were worn (this is rare in central FL where I live) it would be no more problem than a mountain gun that some carry. I live in a rural area, and the 44 is often comforting compared to the 357 and if it makes you happy, go for it. I think the idea of the gun is good, and so did Smith & Wesson as they have come out with similar models on their big frame. Compared to them, the alaskan is petite.
By the way, the grip that comes on it is bigger than it needs to be for 44 spl and I changed it out to a GP100 grip which interchanges and makes the overall gun smaller.
Just my 2cents.
