100 years ago…. Posted on 03/29/2011 by B 1911…..3/29… The M1911 was adopted by the United States Army. A good thing. There may be more modern pistols available, but the 1911 has existed for 100 years….for a reason. I own 4 examples of the design, and several variations…I carry one nearly every day. Thank you, Mr. Browning.
