Sorry if this is redundant, and I know it's sort of a dufus question, but I needed to ask since the .40 has more ENERGY than a .45 at the muzzle (only very slightly more), on average, whereas the .45acp has more MOMENTUM/"POWER" (quite a bit more). I'm pretty sure the .40 is more controllable; the .45 less (i.e. the .45 has noticably more recoil), but I want to verify and get multiple opinions, or contrary opinions if that's the case. I'm comparing ONLY these two calibers, and am interested ONLY in the controllability/muzzle flip/recoil, in particularly how it relates in getting back on target faster for follow-up shots, and PARTICULARLY for shot #2, but any string of rapid-fire shots. Is the .40 noticeably more controllable with faster follow-up shots, or not? Only slightly/theoretically, but not noticeably? Or not at all (i.e. the .45 is equally as fast on follow-ups)? Speak GENERALLY in comparing the two cartridges, but if you cannot speak generally without more information, then compare them specifically as follows: SAME size and weight handguns, both 4" bbls, 40 is a 165 grainer (standard pressure/vel, not +P), .45 is a 230 grainer (standard pressure/vel, not +P). Thanks very much. --Dan
