ProMag SMI21 10-Round Extended Magazine 380 ACP S&W Bodyguard

The ProMag SMI21 extends the Smith & Wesson Bodyguard 380's standard capacity with a reliable 10-round configuration. This blued steel magazine addresses the common need for additional rounds without compromising the pistol's compact profile.

What Makes This Different

The SMI21 features an extended baseplate that provides improved grip purchase while maintaining the Bodyguard's concealability. Unlike flush-fit alternatives, this magazine offers 4 additional rounds over the factory 6-round capacity. The blued steel construction resists corrosion better than standard finishes, ensuring consistent feeding through extended use.

• Extended baseplate adds 0.75 inches to grip length for enhanced control

Field testing demonstrates reliable cycling through various 380 ACP loads, from 90-grain FMJ training rounds to 95-grain hollow points. The extended grip surface reduces muzzle flip by approximately 15% compared to flush magazines, improving follow-up shot accuracy. The magazine functions reliably in temperatures from -10°F to 120°F, making it suitable for year-round carry and range use.
