Frequently Asked Questions

What is the main advantage of the Radian Ramjet and Afterburner system for the Sig P365?

The Radian Ramjet and Afterburner system offers high reliability with various 9mm ammunition, easy installation via a single screw, and is 50-state legal because it doesn't use a threaded barrel. It provides a flush-fit design and improved performance.

How does the Radian compensator address heat issues compared to OEM P365 X-Macro designs?

OEM integrated compensators can transfer significant heat to aluminum frames. The Radian system, by using a separate barrel-mounted compensator, creates an air gap, reducing direct heat transfer to the grip module during high-volume shooting.

Which grip modules are recommended for the Sig P365 X-Macro build?

The Icarus Precision ACE offers premium ergonomics with integrated magwell and thumb ledges but is expensive. The Icarus Air is a more affordable polymer option with similar indexing points, while the Radian backstrap adds necessary palm swell.

Is the custom Sig P365 X-Macro build compatible with standard holsters?

Yes, despite aftermarket modifications like the Radian compensator and Icarus grip, the build maintains perfect fitment and concealment with standard Sig P365 X-Macro holsters designed for optics and lights like the Streamlight TLR-7A.
