I would take a .357 sig over a .45. We could argue points and opinions all day if we wanted, but that wouldnt change any ones mind. I like .380, 9mm, .357 mag and sig, 10mm, and .45. To me it comes down to what is comfortable to shoot and meets my needs for its intended use. "Professionals" thought i was nuts for taking a .30-06 and a .35 Whelen to Africa. Apparently they are not big enough to do exactly what they did. Quite effectively I might add. It all comes down to personal preference and comfort.
And that is why I top off my tank. I prefer to fill it up and am comfortable doing so....
