Frequently Asked Questions

Will this fit every P365 model? It fits all 9mm P365 models, though there will be a visible gap below the grip on the standard P365, P365X, and P365-XL frames since the magazine is longer than those grip modules.

Is this a genuine Sig Sauer part? Yes, it’s a factory Sig Sauer magazine, not an aftermarket copy.
