Yes it is a 9mm world and I encourage any one that wants a semi auto self defense pistol to get a couple of 9mm pistols, a bushel basket full of magazines and a good holster, etc. The 9mm is easier for most to shoot well and to learn to shoot quickly, the ammo is cheaper so one might shoot more often, which we all need to do. I cut my teeth on a 1911 .45 ACP and love my little Glock 36. But, I have more 9mm pistols then any thing else, except for .22's. I also carry a Glock 43 or Glock 19 more then any other pistol.
Bullet design is so good these days, we truly live in the age of "super bullets". So for the most part at reasonable hand gun fighting distances for civilian's, it is like hunting , shot placement trumps every thing.
