I installed mine last night, and I'm kind of on the fence so far. It's definitely not a typical Glock feeling trigger. I'll try tweaking the pre-travel and reset screws and see how it feels. I think my Vanek trigger is adjustable as well, but I've never played with the adjustments, so this is a first for me.
I'm not knocking it. I just haven't had time to get used to it, or make any adjustments. But it feels as though there's a lot of stacking, and then it almost breaks with no pressure. It's just a different feel.
