Frequently Asked Questions
Will this magazine fit my standard SIG P320 Full-Size or Carry model?
This magazine is specifically designed and dimensioned for the P320 M17 (full-size) and M18 (carry) variants. While the P320 platform shares a common fire control unit, magazine compatibility can vary between grip module sizes. This mag is optimized for M17 and M18 frames. We recommend verifying your specific grip module size before purchasing to ensure a proper, drop-free fit.
Why does this 10-round magazine have a 17-round body?
California law restricts magazine capacity to 10 rounds. To remain compliant, this factory SIG SAUER magazine uses the full-size 17-round body — which is the standard M17/M18 housing — but is pinned or restricted internally to hold only 10 rounds. This means the magazine sits flush with the grip frame exactly as the original would, preserving the pistol's intended ergonomics and appearance without any compromise to the exterior dimensions.
Can I use this magazine in other states where higher-capacity magazines are legal?
This magazine is sold as a 10-round restricted unit through Goodland Guns in California and is intended for use as a compliant magazine in restricted jurisdictions. If you are purchasing for use in a state with no capacity restrictions, you may want to consider the standard 17-round or 21-round factory P320 M17 magazines instead. Always verify your local and state laws regarding magazine capacity before purchasing any firearm accessory.
