I went through the same decision process. Almost got a G19, but could not get past the "holding a 2x4" grip ergos with my small, crippled hands. The trigger needs some money put into it to be really right. The need for trigger enhancements turned me away from the M&P. I personally don't like the trigger on the SR9. I almost got a Caracal C, then they had a safety recall and none were available. So I focused in on the PPQ and was fortunate to get one of the recent batch of Q9s that hit the market about a month ago and are now just about gone. I haven't had much time with my PPQ yet, but from what I can tell so far I am VERY HAPPY!
