Yes the bersa thunders are da/sa altho i think they have one dao model. The ones i have, have really decent triggers. They are a little gritty for the first thousand trigger pulls or so till the machine burrs work out. But i would say the triggers are much better than what you find in most full size da/sa, glocks, ruger, and sw guns.
