Description
The P320-XCOMPACT SPECTRE is a factory-custom SIG Sauer that hits the sweet spot between a full-size grip and a compact slide. This is for shooters who want a flat-shooting, optics-ready pistol without the bulk of a duty gun. We started stocking this in late 2024, and it has become one of our steady sellers in this category. The key benefit: you get the proven P320 platform with X-series upgrades, a custom Spectre slide, and a compact frame that conceals better than a full-size but shoots like one.
Key Highlights
- Custom Spectre slide with aggressive lightening cuts and X-series serrations — reduces weight without sacrificing strength.
- Factory optics-ready — includes mounting plates for most popular red dots (Romeo1Pro, DeltaPoint Pro, etc.).
- X-Compact grip module with medium size, tungsten-infused polymer for reduced muzzle flip, and 15-round flush-fit magazine.
- Flat-faced X-series trigger with a crisp break and short reset — a noticeable upgrade over the standard P320 trigger.
- Staff note: “One of our most-reordered items — customers come back for a second one.”

What Buyers Ask
Does this come with the suppressor-height sights?
Yes, the P320-XCOMPACT SPECTRE ships with X-Ray3 day/night suppressor-height sights from the factory. They co-witness with most red dots when mounted.
Will this fit standard P320 holsters?
It fits most holsters designed for the P320 compact or X-Compact models with a 3.9-inch barrel. The Spectre slide is slightly wider due to the lightening cuts, so some tight kydex holsters may need a minor break-in. We recommend a holster made specifically for the X-Compact or Spectre models.
Can I use a full-size 17-round or 21-round magazine in this?
Yes, any standard P320 magazine works. The 15-round flush-fit mag is included, but 17-round and 21-round mags will extend past the grip and work fine.
