I'm in the market for a 26 also. I picked up my 19 a couple of days ago, after my obligatory 10 day wait. Love it! I've shot the 26, 27 and the 36 and every Glock other than the .380's. Between your 2 options, I'd probably pick the 26. It almost handles like shooting a larger gun, but with the concealment benefits that come with the smaller size. The 27 is pretty great too. It just hops around a little more. I'm sure you'll be happy with either choice.
I won't have many opportunities to carry in my state, until some laws get changed, but I'm applying for a UT CCW, so I can carry while visiting neighboring states. I'll have to spend some money in those places to show my appreciation.
