Just got a second 43x while I was looking at a Glock 19. I decided I have been carrying a Walther PPS or my G43x IWB most days right now that I had to get a second. Then I traded a pistol I had not shot in 4 years for a Glock 48. I think I am good on pistols. I really see no need to go away from a Glock 19, Glock 43x/48, or Walther PPS. I prefer the G43x but the PPS with 6 round mag makes for a eaiser gun to concel. The nano is even smaller.
