S&W's have one key feature the other DA autos do not: a short trigger reset.
The 39's always pinched my trigger finger between the back of the trigger and frame and would probably do the same to yours, so check that out.
The 5906 kicks very little. The 415 or 410 have alloy frames if the weight is an issue.
One of the better carry guns in the S&W line is the 3913. It shoots well, too. I even made IDPA "Master" with my 3914 (blue instead of stainless), outshooting all the full-size guns there!
HK's are over priced. If you get a Sig, get one with the "SRT," or "short reset trigger." It makes a big difference.
Let us know what you get.
