LBV (Load Bearing Vest from HT). Or a tactical vest, which one can assume includes a LBV.
Load up the vest with your dangerous-situations kit: filter mask, mini air tank or air tube, sensor goggles, longer-range communicators.
An assortment of thimble grenades with fun warheads (tangler, smoke, biochem goodies). Thimble grenades are so small that you can have a box of them that would easily fit into your LBV.
A medikit. Also load it up with exciting drugs and useful poisons. Neural Inhibitors are tiny and can be used to completely paralyze. Also, you can get them past customs because they're obviously medical not weapons.
A laser pistol that can do both beam and pulse. Should also be hotshot-able. Or possibly a flashlight-laser-torch.
If TL is high enough, an omni-blaster if lethality is ever-present. If TL is high, but you have to pretend to be peaceful, a force beamer works great as a mostly-self-defense weapon.
If TL is low, an underbarrel electrolaser on a payload-delivery-type weapon (like a payload rifle, grenade launcher, or shotgun) upgraded with ETC, LP, or ETK.
Karatands built into ballistic armor gloves, or a zap glove.
Some sort of ultra-tech knife (superfine, monowire, vibro, hyperdense, or nanothorn).
Plus all the typical security gear: handcuffs, electronic lockpicks, surveillance devices, etc.
