The 642, P11 and 3913 seem very popular here. I own one of each. Of the 3, the 3913 (3914 actually, same gun, different finish) gets my top vote. Great ergonomics, flat and slim, accurate as heck, and dead reliable. I appreciate the many merits of the 642, I really do, but the 3913/3914 is superior for me for CCW.
