Re: 10mm or .44
Uhh, those videos are not very convincing that a 10mm is better than a 44 mag. It does seem to work well on whitetails at short range, though, no argument there.
I killed my first bull elk (and many mule deer since) with a 44 mag....and it will fire when wet, thank you.
A Glock is a fine gun, no doubt. A 10mm is a fine round, no doubt. But a 10mm Glock does not fulfill the role of a 44 mag revolver, and vise versa.
I think the concept of the question is either incomplete or flawed. A hunting gun is not a conceal carry gun. If you're hunting white-tail a 10mm, 45 acp, or short .357 will probably be fine (and all OK for conceal carry, right?) If hunting at a distance or for game over 300 pounds, the plain fact is a 44 mag will be much more reliable in killing.
I also agree that the .460 is a fine choice, although maybe not as inexpensive or easy to find ammo for.
Just buy 2 guns. There, it's settled. Just tell your wife your good buddy on Sniper's Hide said it was the best way to go.
