Duty weapon: 1911, of course.
Glock in pocket: Kramer Leather Pocket Holster. Outstanding. I started with a 26, now use a 33. It's my general EDC in this holster and BUG carried elsewhere. (The 33 was a poor idea for me - doesn't really do anything a 26 won't with good ammo, and the ammo costs more and is harder to get, plus 10 rounds or so is all the fun to be had with it.)
Glock generally: 17 or 19. Best performers they have. I'd carry one quite happily.
All the information available indicates that if one is stuck with a pistol for a fight, quality loads in 9mm, 40, 45, and anything less common work about the same. There are no magic performers, especially in handguns, and anyone who takes a pistol to a fight they can't avoid is not very smart - that's what rifles are for. The 40 as a round also has issues related to the pressure and severe risk of setback (apparently due to the limited amount of bulet held by the case) - not a problem as long as you understand that a 40 round is only chambered once, then either shot or destroyed.
G22/23 have a poor track record with hard use populations, especially for intermittent hard to replicate malfunctions. Changing ammo, mag springs, recoil springs - nothing seems to work consistently. See, for example, this string:

Hard use folks who know more individually than I ever will have given very positive reviews to the M&P. I have not shot one, but have heard it is one of the most pleasant to shoot in .40. I have a friend at NCHP, and have not gotten around to asking how they like the M&Ps because I don't have the time or money to get one. WSP actually started the transition over a month ago, and it was a done deal well before that. They had HK USPs, and I shot a friend's duty weapon a couple years ago. It was not at all bad, but as usual, HK's customer service cost them a customer. I've never heard anything good about HK's CS, and my own experiences would allow me to show you the difference between Tourette's and a choice.
