My only handgun is a Gen 3 G19 and I've gotten to where I don't even carry it anymore due to its size. So I've been strongly thinking about getting a G43 and maybe selling the G19. I really don't shoot as a hobby anymore so the only reason to keep the G19 would be for possibly a better home defense gun over the 43. To complicate matters I know someone selling a used Gen 4 G23 that has less than 500 rounds through it for $380 with 3 magazines. Is this too good to pass up? Is having only a G43 for home defense a crazy idea? Or should I also have a G19 or G23?
