I am thinking of buying a Glock 20 for my son. We will be heading to Alaska this summer and i want him to have a gun to carry. I have a .454 so i am good to go. If i buy him a .454 its great for AK but not much of a carry gun and outside of AK there is not much use for it. If i buy him a 10mm it may not be the best for Alaska but 15rnds of 10mm is alot of fire power. It would also be a good carry gun. Is the 10 dying or holding its own? Thanks for your replies!
