They’re just plain wrong about 1911s though. Those things have been surpassed many times over in every category that you would care about in a hand gun, including reliability. I know a few gunsmiths. They’re always fixing 1911 platforms, well beyond what your would expect for their popularity. Everyone always says “two world wars,” and they were a great gun for they’re era, but there’s a reason they got replaced.
Any boot that can actually be resoled. You might pay a higher up front cost, but they will be worth the investment when you’re putting your third outlsole on them in instead of getting yet another pair of shoes.
Edit: also, the AK isn’t actually cheap to make, it’s just the US market was flooded with surplus guns no one wanted for a good while.
