Like any trigger work make sure that it holds before loading and shooting it. I start by tapping the stock with a rubber hammer, and if it stays cocked then I rap it on the floor a few times fairly hard. I do this with the chamber empty, but with the gun cocked of course.
I went the Rifle Basix route with mine, and have a great, crisp, creep free 1.5 pound trigger. And as hard as I tried I can't get it to go off unless I pull the trigger. If I had a complaint it would be the trigger is a little to light.
