Many folks speak of these guns being built super tuff, over built, tanks...and they are. However, my impression is more of, they are built to perfection so that feeding rounds from a perfect magazine and firing does so much less wear and tear than all the other guns in the marketplace.
I always marvel at how effortlessly they feed. Like butter! Unlike the FNX or 1911 CHU CHANK , and I like both of those weapons.
