Congrats! Sheri has a G19, which I believe is the same frame as a 23 (compact). I know a lot of people who conceal carry with the G19. Certainly, their subcompact models make for better carry pistols. Why not go for the G27 so you can stay in the same caliber? Is it because the 9MM holds more rounds?
Is that a Mark III? It's a freak'n hoot to shoot. It likes hot ammo. It can jam up on the lesser stuff.
