What is most important is YOUR ability with YOUR handgun. Can't hit a broad side of a barn with a .45 - then it's not the gun for you. Same with the 9mm, .357, .40 Cal, 357 Sig, .......
Thanks for posting that, I agree completely. My only caveat would be that if you're using YOUR handgun in a defensive/offensive scenario, YOUR handgun should be chambered in one of the standard service calibers and loaded with proven effective ammunition.
Bottom line... one good shot placed is better than 5 missed shots anyday, anytime, in any occurance.
Better than 100 missed shots. Or 1000 missed shots. You can't miss fast enough to win in a gunfight.
