Frequently Asked Questions

How do you safely remove the slide from a Sig Sauer P365 for grip module replacement?

First, remove the magazine and visually/physically confirm the chamber is empty. Lock the slide to the rear, rotate the takedown lever down, and then remove the slide assembly from the firearm.

What is the Fire Control Unit (FCU) and how is it removed from the Sig P365 grip?

The FCU contains all the serialized fire control components. To remove it, drive the rear frame pin out from left to right using a punch, then lift the FCU straight up and out of the stock frame at a forward angle.

You will need the supplied magazine catch, its spring, and the lock. These components are installed into the designated channel and housing within the new Wilson Combat frame.

Why is a final function check important after swapping the P365 grip module?

A function check ensures the pistol operates safely and correctly after modification. It verifies that the slide locks properly, the takedown lever has tension, and the magazine releases cleanly.
