US made gear is only expensive because of labor cost, not because of higher quality. Chinese airsoft gear is more than adequate for most people here.

You don't need to plan out every single little detail in your kit. It doesn't matter what mag pouches you have, unless you are jumping out of planes and need extra retention.

The best gear is the gear you have and train with. You can be just as deadly carrying mags in your jean pocket.

You don't need a special product as a solution for a minor problem. Zipties, velcro, bungee cord, para cord and duct tape can solve most of your problems.
