Sig Sauer P365-DH3 AXG 9mm 3.7″ Coyote X-RAY3
About this product
The Sig Sauer P365-DH3 AXG 9mm 3.7″ Coyote with X-RAY3 sights is a competition-tuned, optics-ready micro-compact pistol built on the aluminum-framed AXG platform as a collaboration with professional shooter Daniel Horner. Specifically, the slide-integrated expansion chamber is designed to reduce felt recoil and muzzle rise, which improves follow-up shot speed and accuracy. The pistol includes multiple magazine configurations for both concealed carry and competition use.
What is the Sig Sauer P365-DH3 AXG used for?
The P365-DH3 AXG is designed primarily for the shooter who wants a single micro-compact pistol that can serve as a high-performance carry gun and a serious competition tool for events like USPSA Carry Optics. This isn't a duty pistol or a plinking gun; the tuned chamber, competition serrations, and included high-capacity magazines point toward action shooting. The AXG aluminum grip frame provides a secure, rigid platform for mounting optics like the Holosun EPS Carry, which is a common pairing on our range.
How does the Sig Sauer P365-DH3 AXG compare to a standard P365 XL?
The DH3 variant is a more specialized and mechanically tuned version of the standard P365 XL platform, making it better for fast, controlled shooting but less cost-effective for basic carry. While a standard P365 XL has a 3.7-inch barrel and similar capacity, it lacks the DH3's slide-integrated expansion chamber specifically designed to reduce muzzle rise, and it ships with standard flush-fit magazines instead of the 17 and 21-round extended models included here. For a pure carry pistol where cost is the primary concern, the standard XL may suffice, but for shooters wanting built-in recoil management hardware for the fastest possible splits, the DH3 is the superior choice.
What does it weigh and what are the dimensions?
The pistol has an unloaded weight of approximately 25.3 ounces with an empty magazine inserted, which is roughly 4.7 ounces heavier than a standard polymer-frame P365 XL due to its aluminum AXG grip module. Its overall length is 7.2 inches, with a slide height of 5.2 inches that accommodates the extended magazine baseplates. The 3.7-inch barrel is cold hammer-forged stainless steel, and the accessory rail is a 1913 Picatinny standard measuring 1.3 inches in usable length for mounting compact lights like the Streamlight TLR-7A.
Who is this NOT for?
This pistol is not for the new shooter looking for an inexpensive first gun, nor is it for the minimalist who prioritizes absolute concealment over performance. The price point, competition-oriented controls, and included high-capacity magazines add bulk and cost that a dedicated concealed carrier might avoid. If your primary use is pocket carry, a firearm like the standard P365 SAS is a more suitable option. Similarly, if your budget is under $800, you'll find better value in a Stevens 334 Rifle for hunting or a basic polymer-framed pistol.
What's in the box?
The box includes the pistol itself, one steel 17-round flush-fit magazine, two steel 21-round extended magazines, a SIG-LOC optic mounting plate kit, a cable lock, and the owner's manual. Notably, Sig Sauer does not include a hard case or holster with this model, which adds $50-$100 to the initial setup cost compared to some competitors that bundle them. The three magazines provide a combined 59 rounds of immediate capacity, which is ideal for a training session or match without constant reloading.
Is the Sig Sauer P365-DH3 AXG worth it at $1,253.99?
Yes, the DH3 AXG is worth its price for the shooter who will actively use its competition-specific features, but it represents a poor value for someone who won't. The premium over a standard P365 XL (roughly $400) buys you the DH3-tuned slide, the premium AXG aluminum grip, and three magazines that would cost over $150 separately. If you plan to shoot USPSA matches, run regular high-round-count drills, or simply want the most mechanically advanced version of this platform, the investment is justified. If you want a reliable over-under for clays instead, consider the Stevens 555 Sporting O/U at nearly half the cost.

Pros & cons
What works
- Weighs 25.3 oz — provides a stable, recoil-dampening platform compared to polymer frames.
- Includes three steel magazines (1x 17-round, 2x 21-round) for 59 rounds of immediate capacity.
- Slide-integrated DH3 expansion chamber reduces muzzle rise for faster follow-up shot splits.
- SIG-LOC optic footprint allows direct mounting of popular micro red dots like the Holosun EPS Carry.
Trade-offs
- No hard case or holster included — adds $50-$100 to initial setup cost for proper storage and carry.
- Coyote Cerakote on slide shows holster wear faster than Nitron or PVD finishes — expect finish marks after 50+ draws.
- Aggressive DH3 slide serrations can chew up softer gloves during extended, high-volume drills.

Frequently asked questions
- Is it compatible with a Holosun 507K?
- Yes, the P365-DH3 AXG uses the SIG-LOC compact footprint, which is directly compatible with the Holosun 507K, 407K, and EPS Carry without an adapter plate. You will need to use the specific screws provided by Holosun, as the Sig Sauer plate kit screws are often too long. Mounting and zeroing the optic typically takes about 15 minutes with a proper torque wrench.
- Does it fit standard P365 XL holsters?
- Mostly, but not universally. The AXG grip module and slide lightening cuts are dimensionally identical to a standard P365 XL slide, so most kydex holsters will fit. However, the DH3's more aggressive front and rear slide serrations can sometimes cause a slight catch in holsters molded for the standard XL's smoother slide. We recommend checking with specific manufacturers like Tier 1 Concealed or T-Rex Arms for confirmed compatibility.
- How long does shipping take to an FFL?
- Processing and shipping from our warehouse to your selected Federal Firearms License (FFL) holder typically takes 3-5 business days. Once the firearm arrives at your FFL, you must complete the required Form 4473 and pass the National Instant Criminal Background Check System (NICS) check before taking possession, which can add another 1-3 days depending on state laws and FFL workload.
- Can I return it if there's a mechanical issue?
- Yes, Ironclad Armory accepts returns for firearms with legitimate mechanical defects within 30 days of delivery. The firearm must be unfired and in its original packaging, and you must coordinate the return through an FFL holder. For warranty work on Sig Sauer firearms, we typically direct customers to Sig's own lifetime warranty service, which has an average turnaround time of 10-14 business days for repairs.
- Does this work with a Streamlight TLR-7 Sub?
- Yes, the integrated 1913 Picatinny rail is designed for compact weapon lights. The Streamlight TLR-7 Sub for Sig P365 (model 69430) attaches directly without issue. The rail section provides 1.3 inches of mounting surface, which is sufficient for a secure lock-up. We've found zeroing a pistol with this light attached does not affect point of impact at defensive distances of 25 yards or less.
