I handled both of them today. The P9 is very small and very simple. I think the slide is the same as the K series and the frame seems narrower and definitely lighter. Only complaint is the slide lock lever. It seems to stick out further than it has to...$509. The 36, as you know, is the same length and height as the 30 but a good bit narrower and holds 6+1. The guys in the store and a few other guys who looked at it didn't seem to care for it, but I fell in love. Nice grip and Glock pointable. No complaints. I think I found my .45... They were holding it for a customer who wanted to have the first one, but if he did not bite, I could have it. I've got my fingers crossed. $529...
