I currently carry the GLOCK 19 (Gen 4) as my duty sidearm and off-duty. I've never found concealment to be an issue. I was informed a couple weeks ago that I will be issued the new G45 (Gen 5) in the near future so I went ahead and purchased the G19. When I am issued the G45 I'll just move the G19 to the safe and it will become my full-time CCW.
