The Beretta 92FS is a semi-automatic service pistol chambered in the 9x19mm Parabellum cartridge. Accurizing is defined as "the process of improving the accuracy of a firearm." The 92FS is the standard US Military sidearm. This means that millions of people's lives depend on this weapon system on a daily basis; therefore, accurizing this weapon is of supreme importance.
Projectile Propulsion Consistency
Select a premium brand of ammunition. The most accurate, well-maintained pistol in the world will still be unreliable if the ammunition it is paired with is not manufactured to high, consistent standards.
Take your weapon's projected use into consideration when selecting an ammo type. If your weapon is going to be used primarily for defensive operations against human aggressors, +P jacketed hollow points are better than round-nose full metal jackets.
Use the same ammunition every time you shoot. This is very important as it allows you to become intimately familiar with your weapon and its operation. This, in turn, allows you to notice subtle differences in the function of your pistol that could indicate some type of malfunction or wear on specific parts.
Add enhancements to your weapon. These can include aftermarket grips, skate deck tape on the slide, picatinny rails, laser sights or any number of other options. Remember, though, that accessories do not make up for lax training.
Add accessories that you need--not those that look cool--to your weapon. Do not go overboard. An example would be the pistol bayonet. It looks pretty scary, but it serves no real purpose except to take up rail space that could have been used by something useful like a flashlight or laser sight.
Use a good holster. Your holster is likely the most important weapon accessory you have, so don't settle. Buy a solid, reliable holster that is specifically designed for your Beretta. This will improve your draw, which improves accuracy.
Ensure that your hand is as high on your weapon's grip as possible when you draw it. This greatly reduces muzzle climb and the risk of an incomplete slide cycle due to absorption of kinetic energy in the wrist.
Place both hands on your weapon at full extension. They should exert equal force on both sides. This prevents the weapon from recoiling to one side or the other, and, when used with a good, high tang grip, can reduce muzzle rise to almost imperceptible levels.
Plant your feet. They should be about shoulder-width apart, and your knees should be slightly bent. This improves stability, which has a significant effect on accuracy.
Tolerances and Harmonics
Ensure that you do not install anything that could impede your weapon's function when replacing an original manufactured part. Also, ensure that the aftermarket part does not get in the way of other moving parts within the gun.
Test your weapon with both the original and aftermarket parts at your firing range. Be methodical. Your 92FS is a very complex group of overlapping systems, and the slightest intolerance could lead to inaccurate discharges or even complete weapon failure.
Do not concern yourself with harmonics when referring to pistols. As long as all parts conform to factory original specifications, your weapon will function efficiently.
