John,
I picked my Robar RR model today. It is a beautiful gun but something unusual happened when I dry fired it: The trigger did not return. Instead, it was "stuck" as though it were in single action mode of a DA gun. When I racked the slide, against empty magazine, trigger went back into DAO mode.
My perception is that the Robar coating might be a factor, due to already tight tolerances. However, I defer to the forum. What I don't want to do is fire the gun if this issue is rightful cause for concern.
Comments please.
