Managed to get some range time in on Friday evening and a little yesterday, jut shy of 300rds down range I did have one issue where my hand slipped up an engaged the slide stop, but other than that it's buttery smooth and very accurate.
The ambi. safety is a little on the stiff side but I've been working it on/off for the last three days and it's starting to loosen up.
IDPA match on the 24th should be a good indicator on how the gun runs at speed. I did a few stages of multiple targets on the move and stationary transitions and the gun just flat out runs. I'm working on keeping my elbows bent a little and it really does help mitigate recoil.
