I don't believe there has been a handgun as tested and brutalized as the 1911 design. Think about it, this handgun started life in 1911 and was issued up to and including 1985 and afterwards.
Now I can't speak for foreign designs and their storied history's. But at least for an American handgun, to have gone through the torture, abuse, neglect from the trenches of WWI, every theater of action in WWII, from the jungles of the south pacific to the deserts of Africa and the urban actions in Europe, the frigid cold of Bastogne. I could go on and on, not to mention it's use in every conflict afterwards, Korea, Vietnam, Panama, Kuwait/Iraq.
I just do not believe there has been a handgun that has experienced so many years of the most brutal environments available and still garner the respect and praise that this 1911 design has earned.
Really, just stop and think about that........amazing!
