Thanks for all the feedback. I drove around town last night until I could find a 2.0 to hold and see how the upgrades felt in my hand. Immediately I noticed the grip- aggressive, but not catch threads on your T-shirt all day aggressive. Just about perfect for a factory gun I'd say and I would see no need to further mod the grip especially for a 9mm. With regards to the trigger it is noticeably lighter- probably just under 5lbs guessing. There is still quite a bit of overtravel, and the pre-travel was even further than my Gen1. It does have an audible reset and you can feel it dry fire, but I doubt it'd be enough to pick up on during multiple shot drills live fire. Trigger reset is muscle memory for me anyway, so I'm not sweating it. For comparison purposes I asked to see a performance center shield that was in the case as well, and the pull weight felt identical but the pre/over travel was much crisper on the performance center.
I'll probably go ahead and pull the trigger so to speak. I think I'd prefer a Performance Center model, but I definitely don't have the patience to wait for it. When I get it in my hands, I'll report back to see if the backstraps are backwards compatible or not.
