"The reality is the US military didn't replace the 1911-A1 with the M9. Technology caused the battle handgun to become obsolete."
I don't know where you get your information from, but I will kindly disagree on this statement. I also don't think the TRP is the king of all 1911's, yea, its a good gun, I had 2 over the years, last one was a TRP Operator, didn't shoot or function any different then my SA loaded 1911. But to get back to your statement above, there were many reason why they replaced the 1911, one I remember was the army didn't buy any new handguns since 1955, so there is more to the reasoning of why the 1911 was replaced, just saying.
