If you were limited to only ONE auto round, what caliber would you choose and why?

Whichever one you can shoot REALLY well and afford to shoot often would be your best bet.............shooting is a perishable skill. You might shoot a bigger gun almost as good some of the time (compared to a smaller one), one that you shoot well MOST of the time would be your better choice.

45 ACP. The most proven handgun battle cartidge in America's history and the most potent as far as Terminal Ballistcs. This is undisputed by those who have done thier homework, and no I won't do it for you !

Keeping in mind that handguns generally offer poor incapacitation potential, bullets with effective terminal performance are available in all of the most commonly used duty pistol calibers—pick the one that you shoot most accurately, that is most reliable in the type of pistol you choose, and best suits you likely engagement scenarios. Since basically all the standard service calibers work when fed good quality ammunition, the platform picked tends to dictate the caliber. For example, Glocks and Sigs tend to run best in 9 mm; the S&W M&P is the first .40 S&W pistol that seems to offer an ideal ergonomic and shooter friendly package; while a properly customized 5" steel-frame single-stack 1911 in .45 ACP is a superb, unparalleled choice for the dedicated user willing to spend a significant amount of money to get it properly initially set-up and considerable time to maintain it. For folks who want a .45 ACP pistol, but don't want to invest the funds and effort into getting a good 1911, they would be better served with a S&W .45 ACP M&P or HK45.
