The trigger takes a little getting used to. It's kind of like the Glock and XD triggers, in that it has to be cocked first before it will fire. Retracting the slide a 1/4" of an inch is enough to accomplish this. I think the pull is mentioned as being around 7lbs on the Walther website, but I'm not positive. There really isn't much takeup before you start feeling the weight of the trigger. I'd say it starts within an 1/8" of trigger movement. I'm not sure it's possible to stage this trigger like you would with a DA, there just isn't enough movement for that.
