Does anybody have the specs of each of the 44 mag barrels? I mean velocity etc. I've always wanted a longer barrel option for my .50 DE and thought it would also be nice for it to be 44 mag so I've got another ammo option (anybody got any 44 mag mags for sale?) Anyhow, I got to make an educated decision on if it's gunna be the 14" or the 10" and I can't seem to find the info online comparing the two. And I'm assuming both of those would work on my Mark XIX .50 paired with the correct mag.
