I have owned a Glock 17, M&P, Sig P226, XD, and CZ-75B in 9mm. I have also spent time on P99's, Beretta 92's, and H&K P30's. All things considered, I would get a S&W M&P9 FS with the APEX DCAEK. If you want something with a hammer, get a P30. Read the following threads and you will be well informed by some very experienced and knowledgable people:
Which 9mm Pistol?
