Ok I just wanted to give an update. I went a different direction.

I found a CS with DLC barrel, so I went ahead and jumped on it. It'll be a few weeks before I can even pick it up, but once I can put some ammo through it I'll share my thoughts. I went with the CS cause it looks to be between G19 and G43X sized, and I imagine Staccato will probably be switching over to CS mags with future designs (if I end up buying another bigger one later).

I have no 2011 mags yet, so hopefully my assumptions will come true and I can just stock up on CS mags.
