You will be amazed at how accurate that little guy is. My home range starts with targets @ 11 yds. and off a sandbag, it's not hard to shoot one ragged hole from a 26 at that distance.
Personally though, consider what you want it for. Is it for carry, home defense or just for trips to the range? If it's just for trips to the range with maybe an occasional carry, I'd say go for the 19. For self defense, I'd rather have a .40 or .45 caliber; therefore I'd go with either a G27, G23, or a G30, G36.
I own all the above mentioned guns, but I carry the G36 24/7. Good luck with your search.
FWIW: the recoil on the .45 is actually a little less than that of the two 40 calibers.
