Yeah some mag pouches are mad expensive. I went with a black scorpion gear copy from amazon. 4 mag pouches for about $40 which is exactly what you need for production. They’ve worked great for about a year now. You can cant them anyway you like.
Belt... You can't go wrong with either Double Alpha Academy or CR Speed belts and pouches. I run the Double Alpha stuff. I find the belt to be stiffer. Their pouches have a thin hanger that allows for more contact that the CR Speed. However, you can't go wrong with either.

If you want to save a bit of money on pouches, you can try these. I ran these for a year and they work well. Just a little harder to setup but once they're on your belt, they're good to go. These are knockoffs to the Black Scorpion pouches. I see absolutely no difference in them. I compared them side by side. No difference.
