Frequently Asked Questions
Does the P938 LEGION require any gunsmith fitting?
No. Our staff has tested this model on multiple frames, and the fit is consistently precise. It’s a true drop-in component with no fitting required, which is a hallmark of SIG’s Legion series quality control.
Is the slide cut proprietary to SIG optics?
The slide is cut specifically for the SIG Sauer ROMEO1 Pro footprint. This is a common and robust pattern, and several other red dot models from brands like Holosun use compatible footprints, offering you solid aftermarket optic choices.
How does the trigger compare to the standard P938?
The LEGION’s custom flat trigger is a significant upgrade. It reduces pre-travel, provides a cleaner break at approximately 6-7 pounds, and has a more defined reset. This enhances shootability, especially in a micro-compact platform.
