Get a G17?

[night]

My local store has a nice used Glock 17. I already have a Glock 19. So, setting aside the perfectly reasonable rationale of buying it because it's a nice Glock - what does a G17 do that a G19 doesn't? what does a G17 do better? why own both a G19 and a G17?

It holds 2 more rounds.
It has a longer sight picture, so is a little more accurate shooting at speed.
It would be better for a duty gun.
It would be nice to own all the 9mm's
You would have more fun with a 34 though.

Some people's hands are too small for the 19, but fit very well on the 17.
