Looking at all three. I'm leaning more towards the G17l and G34. I know, longer barrel = slower draw and other things, but my plans after buying the gun are to shoot a lot of paper. And maybe a bad guy if they ever creep in through the window 
SEriously though, which would you suggest? This will be my frist hand gun, and I'm figuring that whichever I go with, I plan to keep a while. I've shot my buddy's G22 a few times and like the .40cal, but I think I want to go with a 9mm simply because it'll be cheaper for me to shoot.
I guess I should also throw out there that I'm liking the 17l/34 more since they seem to be more accurate with their longer barrels (easier for sighting, higher velocity).
So, which would you recommend?
