The simple controls and blowback operation contribute to an intuitive shooting experience, with many finding it easy to learn and operate, even for novices.

Durability is another strong point, as the M3's robust design allows it to withstand harsh conditions, a trait praised by military and civilian users alike. However, some complaints arise regarding its accuracy and effective range compared to other submachine guns, with a tendency for less precision at distance. Additionally, the open-bolt design can lead to issues in very dusty environments.

Overall, the M3 "Grease Gun" garners respect for its reliability and performance in close-quarters situations, while users appreciate its practical design, though some seek enhanced accuracy and refinement.

The M3 "Grease Gun," primarily used during World War II, is chambered for the .45 ACP (Automatic Colt Pistol) cartridge. This caliber is renowned for its stopping power and effectiveness in close-quarters combat. The standard ammunition is the 230-grain full metal jacket (FMJ), which offers reliable feeding and performance.

While the M3 is primarily designed for .45 ACP, it is compatible with various brands of ammunition, including Federal, Winchester, Remington, and Speer, as long as they adhere to the .45 ACP specifications.

For optimal performance, using high-quality FMJ rounds is recommended for target practice due to their reliability, while jacketed hollow points (JHP) can be used for self-defense scenarios, offering expansion upon impact. Subsonic ammunition is also an option for suppressed operations, providing reduced noise while maintaining effective terminal ballistics. Regular maintenance and quality ammunition are essential for the M3's reliable operation.
