EXTREMELY easy to walk (IMO)
3 screws to adjust trigger
My top screw fell off, but it was not big deal.
I bought this about a year ago... maybe a little bit less...
I love this trigger in comparison to my previous trigger. I am not sure if it was a trinity trigger, or maybe a wanna be... but my point is, that this is better than my previous experience. this trigger is like and easy to walk. There are 3 screws in total: 1) the top screw, 2) the "stopper" in the middle of the trigger, 3) and the screw that pushes the button the on board to shoot. These three screws are all you need to get it so that it is perfectly adjusted the way you want it to be. Although i do recommend that you put tape of some sort on the stopper screw to avoid it falling off or continuously unscrewing.
Buy it. It is worth it.
I got it for a cheap price off of the internet.
