The new V2 adapter is designed to mirror the factory SIG basepad. This updated version offers better compatibility with the use of a magwell and total height when installed on an X/XL magazine body is identical to the factory X-Macro magazine. All orders from October 25, 2025 onward will receive the V2 adapter.

This adapter lets you use your existing P365X or P365 XL magazine in a factory Sig Sauer P365 X-Macro grip module. Not compatible with standard P365 10rd magazine (see my other listings for that adapter). This does not increase capacity!

You will find this adapter is easy to install like the original floorplate.

This listing is for the adapter / extended floorplate only. The magazine and grip pictured are for demonstration purposes only and are not included. Additive manufactured in the United States.
