Frequently Asked Questions
Which S&W M&P models is this magazine compatible with?
This ACT-MAG is designed for the full-size Smith & Wesson M&P chambered in 9mm Luger. It is not recommended for the M&P Compact or M&P Shield, as those models use different magazine dimensions. Always verify compatibility with your specific M&P variant before purchasing.
Why does a 10-round magazine have a 17-round body?
To maintain the ergonomics and grip length of the original full-size M&P, this magazine uses the same 17-round body length but is blocked and pinned to hold only 10 rounds — the maximum allowed under California law. This means the magazine seats flush with your grip just like the standard factory magazine, preserving the feel and handling of your firearm.
Is this magazine legal to purchase and use in California?
Yes. This magazine is specifically configured for California compliance, holding a maximum of 10 rounds. It is sold by Goodland Guns, a California-based retailer, and is legal for purchase and use within the state under current California magazine capacity regulations. If you have questions about local ordinances beyond state law, consult a qualified legal professional.
