Holster advice

Looking for some holster setup advice.

I’ve previously been using a Carnivore holster mounted to a Boss Hanger with a Tek-Mount quick release for my shadow 2. When I bought a PDP, I kept things simple and picked up a GT Holster setup with one of the Tek-Mount insert discs already installed.

The issue is that every time I draw, the holster flexes/bends outward pretty significantly before the gun comes free. It doesn’t feel very solid compared to my Carnivore setup.

My Carnivore doesn’t do this, and I’m assuming that’s because the retention is much lower, but I’m not sure. Has anyone run into this with a GT holster and Tek-Mount setup? Any tricks to stiffen it up or improve the draw?

I’d like to keep using this PDP holster because I use it for two guns and the amount of reholstering and movement involved makes the setup really convenient.

Any suggestions would be appreciated.
