Look at how your safety and trigger work, on the MilPro's the left side of the frame has a tab that comes up and moves with the trigger. I'm sure the safety drops, not allowing it to come all the way back and fire. Now if you pull the trigger past the point where the safety comes down to engage, then of course it will still have that last bit of it's range of motion allowing it to fire.
Use it as it's intended, finger off the trigger before you engage the safety.
