Update: I was able to swing by my FFL and pick up the P-09. And was somewhat surprised to find that it was configured to SA. Luckily for me I was able to consult the armorer's manual I ordered, studied some videos and made the switch, and not without blundering a couple of times along the way. I just consider that part of the learning curve. I'm thinking really hard about doing the CJW trigger upgrade for both my P-07 and the P-09. I've shot the P-07 enough where the trigger has smoothed out though.
