I'm selling my P239 and hopefully buying Tybalts Glock when he PM's me back. I've gone back and forth between the two mentioned and own a full size Spec Ops M&P 9 and love the compacts as well. A side benefit of getting the M&P is that all your full size mags will fit the compact as well. I had leaned that way but I'll probably end up getting rid of my M&P and getting a Glock 17 so that benefit wasn't worth it to me. The P239 is a nice gun and fits me very well but I want something with a consistent pull from shots 1-2 and a bit more capacity.
