Verify Before You Buy

Confirm your P320 model, caliber, magazine type, magazine capacity, grip module size, spring requirements, magwell clearance, and state or local magazine restrictions before ordering.

Compliance & Fitment Warning

Magazine capacity laws vary by state and locality. It is the customer’s responsibility to know and follow all applicable laws. Incorrect base pads or extensions can cause feeding issues, poor seating, or unreliable lockup.

A magazine extension should add function, not problems. Verify before you build the stack taller.
