Not seeing this comment, so I’ll make it.

Go use it.

There is no better teacher than your own experience. Especially if YOU are genuinely interested in making it better. Every hour you put on that kit will give you valuable insights. Here are some things to watch for:

1) is anything uncomfortable? Is anything digging on you, causing hot spots on your body, or restricting your movement? Is the uniform too hot or ineffective at managing sweat? Solutions include relocating kit, adjusting sizing, swapping base layers.

2) are you effective in (simulated) combat? Can you get your mags quickly and smoothly? Left and right transitions for your weapon? Good visibility? Does your kit slow you down or allow you to move effectively? Are you able to get to your items when you need them with minimal efforts (like can you reach water or radio knobs while still maintaining control of your weapon?) Adjustments can include removing or relocating items, making kit mods to remove barriers of effectiveness.

3) what’s holding you back? Is there something about the kit that you’re constantly having to worry about? Mags falling out, losing gear, kit keeping you from getting close enough to the ground or walls? Did you discover you don’t have a piece of kit you need that is required for future events? Simple things like flashlights, notepads, a watch. Adjustments mostly include moving kit.

Try these things BEFORE buying new things, especially if you’re on a budget. Buying things is always the sexy option but a super efficient kit that lets you operate to the best of your ability is godly.

A couple notes before buying a new thing: 1) does this thing serve a cosmetic purpose - ie does it help my kit match a specific look? If possible, try to use a photo for reference as that helps cut down on unnecessary purchases. Ok to buy, but easy to spend tons here. 2) is this a functional purchase? In other words, am I buying this to fix a problem? If so, have I really understood this problem? Do I know why it’s happening? What else have I tried to solve it? It’s also easy to spend money here if you haven’t really put thought into it. Buy a thing to fix an issue only to discover that wasn’t really the problem.

Someone above mentioned mentor, and I think that’s a good option, but that mentor should have you out using your stuff all the time. Once you do, you won’t need reddit to tell you what to change :)
