Mike PGS,
Nope. Never.
I carry a Glock 17 and a couple of spare magazines having arrived at that arrangement years ago and I don't waste my time constantly debating and re-analyzing my decision. Pick what suits you and stick with it.
The caliber (assuming it to be an acceptable "service" caliber), ammunition, type and brand of the gun that you are carrying for the purpose of CCW/SD/HD are but a small part of the overall "equation" when it comes to defending/protecting "you and yours" and "me and mine".
Anyone who believes that the most important aspect of their "plan" should center upon their carry piece and the ammunition contained therein, is in need of a "very serious rethink" since the most important aspect of anyone's "plan" for survival should be that of the tactics that will be employed to first avoid, and if pressed, successfully resolve the inevitable threat(s) to ones' safety and welfare.
The most important and powerful tool that you possess lays smack dab between your ears and just behind your eyes and if you've successfully programmed it with the right "software" (training) you can avoid 99% of the trouble headed your way by remaining vigilant and listening to that voice in the back of your head that keeps saying, "Something just ain't right here" when the circumstances start to go "sideways".
Case in point:
You stated above:

The other day my girlfriend, our four month old, and her friend and her friends young son were out and there was a man acting very odd, just hanging in front of an empty store. A few minutes later he was standing behind the car, hands in his pocket not really doing anything. Anyways he was just acting funny, not really doing anything but my thoughts turned to "I sure wish I had a gun on me in case he tries something", yet this time I also thought "What if there were six of them?"....
You didn't need a gun to resolve this one. The simple and best answer, is that one or six of them, would be to leave the area and return at some other time if need be once the danger has departed. Sure it is inconvenient, but being dead is worse. You can always come back, death is permanent.
Wishing that you had a gun on you, "in case he tried something", tells me that you stayed well past the point of noticing the potential problem and resolving it by leaving. Even if you had a gun "on you", leaving would've still been the best way to resolve the concerns that you've expressed above. Why stick around waiting for trouble to catch up to you? Rather than exercising questionable judgement by standing there and wondering if the threat will materialize, leave. It is that simple.
So, choose your gun and ammunition, then get some professional, competent training. It'll be the best money you will ever spend.
