I had one - was my favorite "glock" due to the grip angle but it had a few things I didn't like:
Price - not worth it IMO (I'm not against expensive pistols, just don't see the extra benefits over some customization for a LOT less).
Trigger - the new "pro" flat face trigger left a lot to be desired (pre travel, break, etc). I got a deal on a Zev fulcrum and it was MUCH better
Holsters - had a hard time finding one that fit when my usual G17 didn't fit great and needed modification
So, I sold it to a buddy who loves it. I went for more competition oriented stuff...but will look again when they have a G19 sized option
