Frequently Asked Questions

What is the main advantage of swapping frames on a Sig P365?

The primary advantage is the ability to change grip ergonomics. The Sig P365's Fire Control Unit (FCU) is the serialized part, allowing users to easily swap grip modules like moving from a standard P365 to a P365X for a more comfortable feel or increased magazine capacity.

How do you safely disassemble a Sig P365 for a frame swap?

First, ensure the firearm is unloaded. Then, pull the trigger, lock the slide back, slide the take-down lever down, and release the slide. The Fire Control Unit (FCU) can then be removed by taking out the rear pin.

Is the Sig P365 FCU the serialized part of the firearm?

Yes, the Fire Control Unit (FCU) is the serialized component of the Sig Sauer P365. This design allows for simple and legal frame swaps, as the FCU contains the legal definition of the firearm, not the grip module itself.

What tools are needed for a Sig P365 frame swap?

For a standard Sig P365 frame swap, you will primarily need a small punch tool to remove the pin holding the Fire Control Unit (FCU) in place. No specialized gunsmithing tools are typically required for this straightforward modification.
