Best TIPX Holster for my vest. (Dual Pistol)

Hello Friends,

I'm looking for TIPX holster that can be attached to my vest.

Tried Leg holster, but it somehow hit my banana, so I stopped using it.

Therefore, I'm looking for some good holster than can attach to my vest nice and tight (around my waist).

Any suggestions?
