ScarFab94 does a go over of the Universal Hardshell Holster that is available at Begadi. This is what the German retailer says about this product... "The universal holster put an end to the eternal holster search and dozens of different holsters on plate carriers and vests!

With 3 screws and an adapter plate you can adapt the holster to almost any weapon!
The holster is made of a tough plastic that is perfectly matched for this application.

With two Phillips screws you adjust the depth / thickness of the holster to your weapon. Use another Allen screw to adjust the position of the lock to the weapon! In the event that you use a weapon with a very narrow trigger guard / trigger guard, a small plate can also be installed to reduce the size. The Allen keys required are included with the holster as well as the adapter plate.

The holster comes with a sturdy, easily adjustable belt clip as standard. Under the unscrewable belt clip there is a holder for standard adapters from CYTAC, Amomax and IMI. For Molle vests we recommend the AMOMAX Molle / PALS adapter for hard shell holster [AM-MA]

Models with a lower rail (e.g. Secutor Rudis, P226 models with rail etc.) also fit into the holster - as do models with a somewhat more common design than the original (e.g. Cyma AEPs)."
