When I was young and stupid, and long before the days of forums such as this, I read gun magazines. Jan Libourel, Dave Arnold, Mas Ayoob, and others convinced me that "wondernines," as they were then called, were the only way to go for defense guns. The 1911 design was obsolete, totally unreliable, and almost criminally dangerous if dropped or pointed at a bad guy.
I bought a SIG P226 and trotted off to a class with a localish instructor, who also happened to be a multiple-time graduate of Orange Gunsite. I was quickly shown the error of my ways, and was exposed to the One True Way. I traded the SIG for a Colt Commander which saw me through a course with Chuck Taylor. I started winning local IPSC-style matches after that, Commander in hand.
Funny thing, when I showed up at LFI-I, Mas didn't sneer at my Commander...though he was packing a P226!
The very same Commander rides on my hip daily, fourteen years later.
