Frequently Asked Questions

What tools are needed to install a Sig Romeo1 Pro on a P320?

You will need a 3/32 Allen key for the optic plate screws. A torque wrench, such as Fix It Sticks with appropriate limiters (e.g., 25 inch-pounds), is highly recommended for precise tightening. A hammer may be needed for gently tapping stuck screws.

What is the recommended torque specification for the Sig Romeo1 Pro?

Sig Sauer recommends a torque specification of 30 inch-pounds for mounting the Romeo1 Pro optic. The instructor in the video uses Fix It Sticks set to 25 inch-pounds, biasing the optic forward to account for recoil.

How do you remove the optic plate screws if they are stuck?

If the optic plate screws on a P320 are stuck, the instructor suggests gently tapping the 3/32 Allen key with a hammer. This can help break the thread locker's grip without stripping the screw head.

What safety precautions should be taken before installing an optic on a P320?

Before starting any installation, always perform a thorough safety check to ensure the firearm is completely unloaded. This includes removing the magazine and visually inspecting the chamber to confirm it is clear of ammunition.
