In stock now at Primary Arms for $79.99 ($75 if you qualify for good-guy pricing).
I bought one directly from Glock when they came back in stock last month, and installed it in a G17 this afternoon. Yes. Immediately yes. This is the closest I've been able to get my Glock to my Gray Guns VP9 triggers that I love so much. Minimal takeup compared to the GG VP9, though the wall on the GPT is much less distinct than on the GG VP9, and overtravel is about the same. Definitely prefer this to the Apex kits I was using, and I've already ordered two more to go in my other two G17s. Live fire tomorrow, hopefully, but I can already tell this is going to be a winner. Not super concerned about the cleaning requirements as I don't shoot that much these days. I do wish it was SCD-compatible, but I was comfortable carrying VP9s AIWB without a gadget for years, so not the end of the world.
