That's a very hard question to answer because it depends on several factors. Bullets from handguns can travel as far as a mile or more.

All bullets "begin losing power" as soon as they leave the barrel- and continue to lose power until they stop. Firearms have a maximum range- how far can the bullet be driven- and a maximum effective range- How far can I HIT a target consistently with this gun/cartridge. Most 9mm pistols have a maximum range of about 900 yards- but at that distance, you cannot reliably hit anything except the Earth. An average max effective range is about 75 yards.
You do not mention which 9 mm cartridge you are asking about. As the 9mm Luger (parabellum) is the most popular handgun load in the world, I assume this is the one? The maximum listed range is about 2200 metres. Actual distance will vary depending on the grain weight of the bullet (for the 9mm luger, from 100 to 147), barell length, and other factors.

The distance a bullet will travel is dependent upon many factors. The three greatest factors in determining the distance a bullet will travel are caliber of the bullet, the weight of the bullet, and the trajectory used when firing the weapon. Many ammunition manufacturers provide "maximum" distances on the individual packages of each type of bullet.
A bit over 3,000 yards, depending on the rifle. Please note tat is NOT the effective, usable range, simply the maximum distance the bullet can travel over a relatively flat surface (with no accuracy)
A bit over 2 miles, depending on the bullet used and the load. This is the maximum range, not the maximum ACCURATE range.
The average 9mm Parabellum pistol has an effective range of about 50 meters. The cartridge has a MAXIMUM range (no accuracy) of about 960 meters.
Beretta is a MAKE of firearm. It does not tell us the model or caliber, which will determine the maximum range that a fired bullet can travel. You need to specify.
Over two miles
A bullet from a handgun can travel, on average, about a mile.
Assuming you mean the distance the bullet can travel, some things are: weather, windage, surface terrain, bullet weight, cartridge specs,
Unimpeded, a .22LR caliber bullet can travel up to 2000 yards. Its effective distance is, of course, much shorter than that.
Depends to some degree on the gun that fires it, and the powder/ bullet loaded into that cartridge. In the case of the M16A2, it can reach a maximum range of about 3,600 meters. Please note that is NOT the EFFECTIVE range- it is simply the furthest distance it will travel at ordinary temperature, humidity, and air pressure- on a relatively level surface,
2-4 miles, depending on the cartridge. That is not the effective range, but the maximum.
