Gen 3 Glock 17...easily the most proven combat pistol on the planet
1911 built by someone I would trust...let's say Jason Burton (although I would probably be pretty happy with a Wilson Combat or Nighthawk...say the CQB Tactical LE, or the GRP, respectively)
I get a third too, eh? Hmm...maybe a .22 or something would be handy. I'd rather leave the last spot open and rotate one gun in and out of it because there isn't really a third gun for me that I care about a lot, but I'd be interested in checking out the PPQ when it shows up, or some of HK's offering if they ever build a trigger I like...
From my perspective, as long as I have a G17 and a quality 1911, I'm good. And the 1911 is just for fun, really.
