I could see this working well mounted on the front of a vest/panel in a vertical crossdraw position. It wouldn't hang out to the side to get caught on anything and you could always mount a bungie to your MOLLE for additional retention.
And... if this is made with Kydex... Kydex can be tricky stuff. If it retains too well you can always heat it a little with a heat gun or hair dryer on high and soften the holster enough to open it up for an easier draw. But Kydex can be a dirt/grit magnet if you are in a dirty environment... but it attracts dirt the same as any other holster.. but will retain it less than other materials. If you pull a rag through it between games you can basically dust it and keep it clean.
