Frequently Asked Questions

Will this magazine fit my Smith & Wesson model exactly?

This Mec-Gar magazine is designed to fit the S&W 5900 Series pistols, including the 910, 915, 659, and related variants chambered in 9mm. Because it uses a 17-round body profile, it drops in flush just like a standard-capacity magazine, maintaining the pistol's original grip length and ergonomics. If you're unsure whether your specific model is compatible, check your pistol's manual or contact Mec-Gar's customer support for confirmation.

Why does a 10-round magazine have a 17-round body?

California law restricts magazine capacity to 10 rounds, but there is no restriction on the physical size of the magazine body. Mec-Gar builds this magazine with the standard 17-round steel shell and blocks it internally to hold only 10 rounds. This means the magazine fits and functions identically to the original, with no need for grip extensions or adapters — a seamless solution for CA-compliant shooters.

How does Mec-Gar magazine quality compare to factory S&W magazines?

Mec-Gar is actually the original equipment manufacturer (OEM) for many Smith & Wesson magazines, meaning the factory magazines shipped with your pistol may have already been made by Mec-Gar. With over 55 years of production experience supplying militaries and major firearm brands worldwide, Mec-Gar magazines meet or exceed OEM standards in fit, feed reliability, and longevity — making them one of the most trusted aftermarket and replacement options available.
