I carried a LW Colt Commander .45 for work long ago; loved that gun--light, accurate, quick. Even had a set of ivories on it!
It finally developed a crack at the slide stop hole. I should have stop-drilled it, which might have saved the frame, but did not. I did manage to find a new frame, and sent it all to a top 1911 smith with instructions to make it 100% reliable with JHP ammo. Alas, it never achieved that. By that time my agency decided that the Commander was "too dangerous" and that since they had not trained me on it I was untrained to boot.
I eventually sold the gun with full disclosure that it was only reliable with hardball. But I miss it to this day.
I looked at the Ruger Commander--which I sort of like-- but these days I find the standard 1911 sufficient for my needs. I also harbor doubts that the quality of 2013 guns are better or more reliable than back in 1975.
Personally I'd like to see Consumer's Report articles on defensive guns being fired 6000 rounds with good defensive ammo with zero failures. Age issues aside, my 1913 Colt would probably do it with hardball.
Just like Congress, it shouldn't be about flash, it's about getting the job done right. Yeah, I'm a dreamer...
