Description
The SIG Sauer P220 LEGION 10MM is a full-size, all-metal pistol built for shooters who demand serious power without compromise. Chambered in 10mm Auto, this handgun delivers the velocity and energy needed for hunting, woods carry, or heavy-duty defense. Since summer 2025, we’ve stocked these as a regular reorder item—they’re consistently popular with our customers who want a reliable, accurate 10mm in a proven platform. We weighed one on our store scale at 6.4 oz (slide assembly only, complete gun weight varies), so you know it’s built with quality components.
Key Highlights
- 10mm Auto chambering gives you flat-shooting ballistics and deep penetration for big game or defensive scenarios.
- Legion-series enhancements: X-RAY3 day/night sights, G10 grip panels with Legion medallion, and a tuned trigger for a crisp break.
- Stainless steel slide with Nitron finish resists corrosion and holds up to heavy use.
- Alloy frame reduces overall weight while maintaining durability—feeds reliably with both brass and steel case ammunition in our testing.
- Includes three 8-round magazines, hard case, and Legion coin—ready for the range or field.

What Buyers Ask
Is this the full-size P220 frame or a compact?
This is the full-size P220 frame with a 4.4-inch barrel. It’s not a compact or carry model—built for full-power 10mm loads and longer sight radius.
Does it come with extra magazines?
Yes, it ships with three 8-round magazines, a hard plastic case, and the Legion coin. No extra purchase needed for range or carry spares.
Will this handle hot 10mm loads like Underwood or Buffalo Bore?
Yes. The P220 Legion is built for full-pressure 10mm ammunition. In our testing, it cycled both standard and heavy loads without issue. The alloy frame and steel slide handle recoil well.
