I've been waiting for this trigger and I'm disappointed.
I was building up an SCT/Zaffiri EDC and figured this would be the one to get. The trigger safety catches on the frame unless you hold your finger at the very bottom and press the tip of your finger in on the safety, just to be able to clear the frame without dragging on it. Very disappointing. I was going to shave some off the end of the safety, so I took it out and of course lost the spring, lol. Oh well, put it back together without the safety now while I decide on what to do next.
The actual trigger press is nice once you are on the wall, it's just getting there is clunky.
