Purchased the trigger because he said it was the 2nd Gen trigger (unadjustable). When I got home, I found out otherwise. Tried to contact about a refund but he disappeared, after saying he would refund my money. On top of the lies and ghosting…the trigger does not work and has tons of grit in it. I should’ve known better than to deal with someone with this few positive feedback. My loss and I’m out of $100. Don’t make the same mistake I did.
