In the entire history of handgun development, there has never been a period of rapid change like the last 40 years. This is particularly true with automatic pistols. I can distinctly remember a major, colorfully illustrated article on the then-new squeeze-cocked Heckler & Koch P7 pistol. That was in the late ‘70s or early ‘80s. The P7 was a fine gun, but it is long gone and many new shooters have never heard of it. Things change real fast in the world of automatic pistols.
For a time, we were all wrapped up in what was called the “Wondernine Wars,” the intense competition among makers to come up with new pistols that had two major characteristics. Those were a double-action (actually DA/SA) trigger system and a double column magazine. Anything less than 15 9mm rounds was cause for rejection.
