I would recommend a DAA Lynx belt with a ratcheting buckle.
Easier to use, more rigid than the "flexible" belts. More adjustability, can tighten down to your needs with the ratcheting buckle. If you get really fat or lose a lot of weight, you can remove links easily. Lots of colors and you can mix and match.

For a holster hangar, I like Henning hangars, either the T-1000 or T-800. They are fairly expensive though, if you want something a bit cheaper the BOSS hangar is also nice.

I like DAA magnetic mag pouches. Bullets out design which is my preferred orientation, they are simple to assemble and use.

Holster is pretty subjective. I have a GX Vice holster. But the lead times are long and inaccurate, and the communication is bad. Red Hill Tactical and Comp-Tac are a couple of other choices.
Despite my Avatar and links, I am not Ben Stoeger nor affiliated with Ben Stoeger Pro Shop. I just buy a lot of stuff there because prices are good and they ship fast. There are other sources to buy if you hate Ben
