Firearms technology has evolved heavily, since the end of World War II, across all platforms. It is debatable on whether the modernization of firearms became simpler or more complex over time. The materials have certainly changed but, due to optimizations for many different end-user aspects, it seems as if modern designs are more complex by comparison to the preceding models. The 9×18 Makarov handgun has an uncanny beauty about it and is very specifically tailored.
Handling your sidearm is like handling your vehicle. If you are negligent or arrogant: a severe cost could result. On the range you could see stove-pipe jams, a wide shot pattern on target, and experience having to take more time reacquiring between shots. In a gunfight these errors could very well get you killed. One training factor is how you grip the handgun. For semi-automatic handguns, I recommend the Combat Grip. This grip is also referred to as the Leatham-Enos Grip, in case you want to do more research, and it’s also commonly referred to as the “thumbs forward” grip.
