Hey 1998,
Welcome from one new member to another! My vote has to go with the Glock 22 or 27, simply because I have had experience and good luck with them ... but I would agree with those responses above mine that you really cannot go wrong with the arms that you have listed. The reason that I have settled on Glock as my weapon of choice is for the very reason that EVERY trigger pull feels the same ... even between calibers unless you do a custom trigger job on one out of the bunch. I have a S&W 4013 (the default "Dick" carry of my local agency) that I absolutely do not like because of its "dual-action then single" mode when decocked and locked. Unless you are REAL uncomfortable carrying one in the chamber, you are ready to rock and roll with the Glock. But, I'll confess, some of my colleagues prefer HK and some of them prefer SIG! I would say, out of all of these, make trigger pull your primary deciding factor. Dependability, repairability, and acquisition are about equal among the 4.
