For carry the 44 will be much easier, lighter, and smaller than the 445. Finding a decent deal on them is rare, and if you think there is a run up on the standard calibers at auction, wait until you see what a clean supermag will do. Believe it or now, pay close attention to the auction sites and make sure you search for any term that might work, I have found a lot of good deals only due to mis-spelling or due to things like listing it as a ".44Mag" rather than a "44 Mag".
