I few days ago I shot 50 rounds of .40 S&W (Glock 22) for the first time. Previously I've only shot 9mm from a Glock 17 or 19. While my accuracy wasn't horrible, it wasn't as good as it's been with 9mm. Although I understand this is to be expected, I don't understand why. Assuming the firearm doesn't recoil until the bullet has left the barrel, why would one's accuracy be less (until proficiency is gained) with a more powerful cartridge? Just to clarify, I'm not talking about the speed of followup shots. My range doesn't allow shots faster than once per second anyway and I was definitely taking my time between shots. Is it simply because I'm expecting a bigger bang and I'm flinching more or was I just less steady for some unrelated reason?
