If chambers came out with the 509T plate (not sure if he has yet) I would be happy. I almost feel like I wasted money on the Acro P2 and even with the new DPO plate it still seems a little askew. The 509T on my Staccato P has been pretty flawless. If I wasn't carrying the gun in a uniformed/open carry in the PNW I wouldn't even worry about the closed emitter optics.
