Hi, you can also use large coin if you dont have enough training ammo. Put it inside magazine like a round. It will lower the "empty mag pin". This helped me a lot in every training.
Have you done a trigger re and re video? I would like to clean up my trigger a little and have only found a few videos on this topic that can get a little confusing. Bad Camara angles and shadows
I don't understand why they didn't upgrade VZ58 after revolution like that, it would be very cheap and fast upgrade which moves ergonomy few levels higher.
