Key Features
- AXG Alloy Grip Module – WHY IT MATTERS: The aluminum frame with G10 chevron panels gives you a low bore axis and a secure, non-slip hold that stays planted during rapid fire.
- Optics-Ready, Ported Slide – WHY IT MATTERS: You can mount a red dot without milling, and the ported barrel helps reduce muzzle rise for faster follow-up shots.
- XRAY3 Day/Night Sights – WHY IT MATTERS: Tritium front and rear with a bright ring give you a clear sight picture in any light, day or night.
- Extended Magwell – WHY IT MATTERS: The flared magwell speeds up reloads, especially under stress or when wearing gloves.
- Three 17-Round Magazines – WHY IT MATTERS: You get a full spare and a backup right out of the box, plus the grip fits your hand without needing a spacer.
Who It’s For
This pistol is for the shooter who wants a compact 9mm that’s easy to carry but doesn’t sacrifice capacity or control. It works for daily concealed carry, home defense, and range training. New gun owners will appreciate the manageable recoil and intuitive controls, while experienced shooters will like the Legion-series upgrades.
Pros & Cons
- Pro: Aluminum grip module reduces felt recoil and improves accuracy compared to polymer frames.
- Pro: Optics-ready slide saves you the cost and hassle of milling.
- Con: The ported barrel can produce more noise and flash in low-light shooting, so consider that if you train in dim ranges.

FAQ
Does the P365 AXG Legion come with a holster?
No, it does not. The pistol ships in a hard case with three 17-round magazines, an extended magwell, and the XRAY3 sights. You’ll need to pick up a holster separately—many users go with Kydex options from brands like Vedder or Tulster for the P365 platform.
Can I use standard P365 magazines in this gun?
Yes, the AXG Legion accepts all P365-series magazines, including the 10-round, 12-round, and 15-round options. The 17-rounders that come with it are flush-fit with the extended magwell, but shorter mags work fine too.
Is the slide cut for a specific red dot footprint?
Per Sig Sauer specs, the slide is cut for the SIGLITE footprint, which is compatible with the SIG Romeo Zero and Romeo Zero Elite. You can also use adapter plates for other popular optics like the Holosun 407K/507K or Shield RMSc.
How does the ported barrel affect reliability?
The porting is designed to reduce muzzle flip, but it can increase fouling on the slide and lens over time. Keep your pistol clean and lubed, and it will run reliably with standard 115-grain and 124-grain ammunition. Avoid very light loads if possible.
What’s the warranty on the P365 AXG Legion?
Sig Sauer backs this pistol with a limited lifetime warranty for the original owner. It covers defects in materials and workmanship, but not normal wear or misuse. You can register your firearm on Sig’s website for full details.
