Frequently Asked Questions

Will this magazine fit my Smith & Wesson SD40 VE?

Yes. This ProMag magazine is designed specifically for the Smith & Wesson SD40 platform, including the SD40 VE. It is engineered for drop-in compatibility with the factory magwell, so no modification to your firearm should be required. Always verify fit before use and ensure the magazine seats and releases correctly before loading.

Why does this magazine have a 25-round body but only hold 10 rounds?

This magazine uses a full-size 25-round body that has been permanently blocked to a 10-round capacity in order to comply with California's magazine capacity restrictions. The blocking is a factory modification — the magazine cannot be legally or easily converted to higher capacity. For California residents, this is the standard-compliant configuration for this model.

Is this magazine legal to purchase and use in California?

Yes. Because this magazine is permanently blocked to 10 rounds at the factory, it complies with California's Penal Code restrictions on magazine capacity. Goodland Guns carries this product specifically for California customers. That said, magazine capacity laws can vary by locality, so it's always a good idea to confirm compliance with your local ordinances before purchasing.
