5 answers. Short answer: yes, Longer barrel improves accuracy. The theoretical accuracy of pistols and rifles depends on rifling, barrel length and bullet quality.

What is the best barrel length for accuracy?

Optimum barrel length for accuracy range Between 16 and 21 inches (40.64 and 53.34 cm). Shorter barrels tend to vibrate violently, resulting in a more consistent and accurate rate of fire. Notably, the energy of each shot is absorbed into the barrel in less time, increasing the level of accuracy.

Does a longer barrel mean more power?

The longer barrel gives the propellant more time to propel the bullet. For this reason, longer barrels generally provide higher speeds, all else being equal. However, as the bullet travels down the bore, the gas pressure behind the propellant decreases.
