How does the .40 Cal. compare to the .45 ACP recoil wise. I shoot a .45 ACP but have never fired the .40 caliber in a short pistol. My wife thinks she may want a pistol and I don't know if the .40 will be too much recoil for her. Is the recoil that much less on the .40. Any ladies that have fired the .40 cal feel free to give your opinion. I'm trying to sort some things out before I sink 900 to 1200 bucks into a new Springfield EMP. I know the 9mm is less recoil but it is also a bit light in stopping power. Thanks
