Training training training.... It took me about 2,500 rounds or so through the little 43 till I felt proficient with it. I'm not talking one hole groups but Coke can accurate at 15 yards and 2 liter bottle accurate at 40. I have always been able to adjust to shooting any handgun tiny or huge, and it bothered me immensely that I was getting gigantic 5" groups at 7 yards and fricken 10-12" groups at 20 yards. So I shot the little f'r till I finally adjusted to it. It took WAY to much concentration and rounds down range to adjust to that little bugger. I finally did but in hindsight with what I spent on ammo, it was not worth it. I sold it and never looked at them again. On a side note never shot a 42 and I had to put many rounds down range to become proficient with the Shield as well.
