Remarkable that they can put out a gun with a PPQ like trigger pull without any sort of trigger safety device for drop safety. I would be surprised if the trigger is Glock or PPQ light.
EAA which is the importer for SAR guns has almost no specs for this model on their website. Why are people assuming it is a copy of the Walther PPQ internally?
The MR9 and SW99 are built on Walther frames. They aren't clones.
But the TP9 is a clone of the P99 action.
None of that suggests what sort of trigger this SAR pistol has.
