CCW options...Shield vs Glock 43

I think I'm gonna treat myself after my CCW class in a couple weeks.

I have a Glock 19, but looking for something a little smaller for CCW needs.

Shield gets a lot of great reviews plus more rounds than the 43....but I do really like the ergonomics of glocks.

I'm of course gonna go get my hands on both and hopefully rent and shoot them if they have them available.

But curious of owners opinions...especially if you have both. Gimme that real world feedback.
