History

The .38 ACP (Automatic Colt Pistol) was introduced by Colt in 1900 for their new Colt Model 1900 semi-automatic pistol. It was the first cartridge to use a small-caliber bullet in a high-velocity cartridge. The .38 Super, on the other hand, was introduced in 1929 as an upgrade to the .38 ACP. It was designed to offer higher velocity and better performance, especially in terms of penetration and stopping power.

Ballistics

When comparing the ballistics of the .38 ACP and .38 Super, it is important to note that the .38 Super offers higher velocity and energy compared to the .38 ACP. The .38 ACP typically has a muzzle velocity of around 1,050 feet per second, while the .38 Super can reach velocities of up to 1,300 feet per second. This difference in velocity translates to better performance in terms of penetration and stopping power for the .38 Super.

Availability

While the .38 ACP is a less common cartridge today, the .38 Super has seen a resurgence in popularity in recent years. This is due to its superior ballistics and performance compared to the .38 ACP. Many firearms manufacturers now offer handguns chambered in .38 Super, making it easier to find ammunition and firearms chambered in this cartridge compared to the .38 ACP.

Recoil

One of the main differences between the .38 ACP and .38 Super is the recoil. Due to its higher velocity and energy, the .38 Super typically has more felt recoil compared to the .38 ACP. This can be a factor to consider for shooters who are sensitive to recoil or prefer a milder shooting experience. The .38 ACP, on the other hand, offers a more manageable recoil, making it a popular choice for shooters who prioritize comfort and ease of shooting.

Use in Competition

Both the .38 ACP and .38 Super have been used in competitive shooting sports such as USPSA (United States Practical Shooting Association) and IPSC (International Practical Shooting Confederation). The .38 Super is often favored by competitors due to its higher velocity and energy, which can result in better performance on steel targets and other challenging stages. However, some shooters still prefer the .38 ACP for its softer recoil and ease of shooting, especially in disciplines that require quick follow-up shots.

Self-Defense

When it comes to self-defense, the .38 Super is often considered a better choice compared to the .38 ACP. The higher velocity and energy of the .38 Super can result in better terminal performance and stopping power, making it more effective in defensive situations. However, the .38 ACP can still be a viable option for self-defense, especially for shooters who prioritize ease of shooting and control over raw power.

Conclusion

In conclusion, the .38 ACP and .38 Super are two popular cartridges with their own unique attributes and characteristics. While the .38 ACP offers a milder shooting experience and is easier to control, the .38 Super provides higher velocity and energy for better performance in terms of penetration and stopping power. Ultimately, the choice between the two cartridges will depend on the shooter's preferences and intended use, whether it be for competition, self-defense, or recreational shooting.
