I have shot the little single stack .380 version. I would have liked Glocks back in the day if they would have had a single stack version, LOL. Good gun.
I had a 27 and I never got comfortable carrying it. Had a couple xds' and have settled with my Kahr CM9 and Shield without the lawyer switch. When I think single stack 9, I long for a 3rd gen Smith 3913. Can't find one though.
