Modular pistols are firearms designed with interchangeable components, allowing users to customize their weapon according to personal preferences or specific needs. This modularity often includes options for different grips, barrels, and sights, making it easier to adapt the pistol for various shooting styles or purposes. These pistols enhance versatility and can improve user comfort and performance. Popular examples of modular pistols include the Sig Sauer P320 and the Glock 19, which offer various configurations and accessories. This design approach appeals to both recreational shooters and professionals, such as law enforcement and military personnel.
