Heavy. Rusty. Not enough bullets.
I know the 1911 is a beloved and comfy handgun. It is obsolete with modern designs. That poor XD (at the bottom on the local lake), shot perfectly, was 1/2 the weight as the other Kimber at the bottom of the same lake, and had twice the firepower in the same foot print.
The 1911 is not at all obsolete. The single action trigger is the the best for those that shoot alot. But it takes special training to use a handgun with a safety. A DA/SA is a great system, but you need special training to be able to adjust to two trigger pulls. The striker fire chosen is a good choice for those that don’t spend the time at the range, ie... perfect for the military. The choice of 9mm over .45 is another discussion.
