Besides needing multiple signatures, multisig also involves complexity in that your change addresses are m-of-n as well.

Sign on Coldcard via SD Card

SD Card is a better airgap, and preferable over signing through USB.

2. Click Save transaction, and save to your SD card
3. Eject the SD card from computer, and load into Coldcard
4. Click “Ready to sign” on Coldcard and confirm transaction details
5. Coldcard will save the signed transaction back to the SD card, but with the -part suffix at the end of the filename
6. Back in Specter, click “Load transaction from file”, and choose the file on the SD card with the part suffix
7. Broadcast
