The 9mm is anemic at best. The only thing it ever had going for it, was the doublestack magazine concept of the '80's, trying to overcome it's stopping ability shortfall. Trying to lump it in together, with proven, able cartridges doesn't help it in the least. So while it maybe good for you, or other novice's, don't say "everyone".
Here's some little bits of data from this month's American Rifleman. This is just one example of many, but it is pretty typical. Note that none of these is labelled as +P.
Gun #1 is a 9mm Springfield Armory SA-35, with a 4.7" barrel.
Black Hills 124 gr. JHP - 1,163 fps, 372 fpe.
Federal AE 147 gr. FMJ - 1,035 fps, 350 fpe.
Hornady AG 115 gr. XTP - 1,140 fps, 332 fpe.
Gun #2 is a Tisas reproduction of a 1911 A1, with a 5" barrel.
Federal SD 205 gr. SJHP - 860 fps, 337 fpe.
Hornady AG 185 gr. XTP - 996 fps, 407 fpe.
Wincester USA 230 gr. FMJ - 742 fps, 281 fpe.
With the exception of the Hornady 185 gr. load, which is light-for-caliber, there is not a whole lot of difference.
Historical note: H. P. White Company tested some 9mm Parabellum loads after WW2. The pistol was a P-38 with a 4 7/8" barrel. Here's just two standard German pistol (not submachinegun) loads:
German Govt. 1918 123 gr. - 1207 fps, 398 fpe.
German Govt. 1941 (Pist.) 124 gr. - 1242 fps, 425 fpe.
The current U.S. military load, as tested by American Rifleman in an M17 pistol with a 4.7" barrel (this is NATO-level, probably between standard and +P levels):
M1152 115 gr. Flat-nosed FMJ - 1326 fps, 449 fpe.
I have yet to see any scientific data that shows a significant difference between the effectiveness of .45 ACP and 9mm Parabellum ammunition in the real world. I HAVE seen a lot of myths and claims based on wishful or sloppy thinking. The "anemic" nature of the 9mm is one of them and the lack of stopping power vs. the .45 is another.
