What would you consider the 5 most significant handguns designed and marketed in the past 100 years? And, more importantly, why? Now, the 100 year limit is troubling for me, because it knocks out what would be my top two choices if were increased the time limit only slightly -- the 1911 and the Smith and Wesson Model 10. Okay, I know technically that there were no Model 10's until the 50's, but re-naming an existing model doesn't count for this contest, as the Smith and Wesson M&P and earlier hand ejector models, which were essentially the same gun, were around since before the turn of the 20th century. Okay, my choices: (1) The Smith and Wesson "registered" .357 magnum, which later evolved into the Model 27. The first .357 magnum revolver -- need I say more? (2) The Browning Hi Power. I am not completely certain of this, but I believe it was the first high capacity 9 mm pistol. It is certainly the first one I'm aware of, and it set the standard for 9mm autos for years. Used by a wide variety of countries militaries for decades. (3) The Glock. Sigh, I hate to say this, but the Glock did, imo, change the firearms industry more than any other gun in the past 50 years. (4) Smith and Wesson .44 magnum, which later became the Model 29. Took handguns and handguns hunting to a whole new level. (5) Hmmm. I've used all the obvious ones I can think of now. I'm going to say the Ruger Mk I automatic. The first gun produced by Strum Ruger, sold tens of thousands, the standard, imo, which reasonably priced .22 autos are judged. Okay, what are your thoughts?
