Sorry Theodore
NO, generally GForce Arms semi-automatic shotguns are not California compliant because they are typically imported from Turkey and are sold as non-fixed magazine firearms, which are illegal to possess or sell in California unless they have been specifically modified to have a fixed magazine. You can often find GForce shotguns listed with a "No" in the "CA Compliant" field on retailer websites, confirming their non-compliance.
You would need to find shotguns that are specifically advertised and sold with a CA-compliant fixed magazine, such as some models of the Kel-Tec KSG or Genesis Arms Gen-12, which are known to have versions that are California legal.
Hope this helps Theodore, please take care and stay safe 🙏

No, the GForce GF25 shotgun itself and its five-round magazine, is not inherently California legal because it is a semi-automatic, magazine-fed shotgun. California has specific laws restricting such firearms, but compliance is achieved by the manufacturer, not by the individual owner changing the magazine. You would need to look for a specific "California Compliant" version of the firearm to be sure it is legal.

Banned Features:
California's assault weapon laws ban semi-automatic shotguns with certain features, which can include a detachable magazine or certain characteristics of the magazine.
