The .40 caliber pistol, often simply termed “.40 S&W,” has established a notable presence in the firearms industry since its inception in the early ’90s. Designed as a compromise between the 9mm and .45 ACP, this caliber offers a blend of power, capacity, and recoil control. Favored by many law enforcement agencies, the .40 caliber pistol is known for its efficient stopping power and robust performance. While trends in the firearm community might shift, the .40 caliber continues to be a reliable choice for personal defense and competitive shooting.
