Well, I simply say go with the 40. The speed is faster than that of a 45 and its power comes very close. A 9mm isn't going to kick barely at all, which is good for targets, but an all around(not hunting big game though)nice pistol i believe should be the 40s&w. Not too much recoil itself. Especially when you compare to the 50 Action Express cartridge fired in a Desert Eagle. Now those are fun.
