I couldn't get all the creep out of the SAV-1, while maintaining 100% confidence in it not slam firing.
The SAV-2 has an extra lever that gives the trigger shoe extra mechanical advantage over the sear. That allows for lighter release weight, and magnifies creep. I can't get mine 100% creep free. Additionally, the SAV-2 has a really janky look/feel to it, the way it flops around.
Frankly, I prefer the accutrigger over both RB triggers I've had, as well as the Timneys and SSS triggers I've felt on other guys Savages.
