At SIG Sauer’s Defense Range Day during SHOT Show 2026, the P365 DH3 stood out as a thoughtful evolution of the P365 platform. The DH3—named for Daniel Horner—doesn’t reinvent the P365 so much as refine it for shooters who want flatter recoil without giving up carry practicality.
At its core, the DH3 starts with the P365 Fuse slide length, but with an integrated compensator. To make room, the barrel is shortened to 3.7 inches, down from the Fuse’s standard 4.3-inch barrel. The result is a macro-length barrel paired with a fuse-length slide, using internal slide porting rather than an external comp. The goal is to mitigate recoil without adding length or requiring bolt-on hardware.
Configuration, Grips, and Capacity
SIG is offering the DH3 in two configurations: a polymer grip module and an aluminum AXG grip module, the latter shared with the AXG Legion. Both use the same upper, so the differences are largely in weight, feel, and price point rather than performance fundamentals.
Capacity remains consistent with the P365 Macro ecosystem. A flush-fit magazine holds 17 rounds, while extended magazines bump that to 21. The grip module is the same Macro-style frame, meaning compatibility with other Macro slides and components remains intact. In short, this isn’t a closed system—it’s very much still modular SIG.
Aesthetically, the DH3 separates itself with lightening cuts on the top of the slide and revised serrations. The changes are noticeable but restrained, leaning more “competition-influenced” than flashy.
Optics, Pricing, and Availability
The DH3 uses SIG’s compact optic footprint, supporting RMSc-pattern optics as well as SIG’s own compact red dots. From a practical standpoint, that keeps mounting simple and avoids adapter plates.

At the time of Range Day, both variants were already shipping. MSRP lands a little over $900 for the polymer version, while the AXG model pushes past $1,200. That pricing puts the DH3 squarely in the premium end of the P365 lineup, competing more on refinement than raw value.
The SIG P365 DH3 isn’t a radical departure—but it doesn’t need to be. It’s a measured step forward for shooters who want an integrated compensator, familiar ergonomics, and P365 modularity in a carry-capable package.
Be sure to check the SIG website for updates, as this pistol is expected to be added soon.

Can anyone point me to a level 2 holster…. I can’t find any
C’mon SIG, where are the exciting new or reintroduced P22x Classic DA/SA pistols? Except for the P220 45 and 10mm, everything is 9mm. No 357 SIG or 40. Not even the old 38 Super or 9mm in the P220. Where is an all stainless steel P220 5″ long slide 45 Legion? We old SIG fans helped put SIG on the map since the Browning BDA of 1978, before SIG even put their name on a P220 for the USA. Not all of us want striker fired guns. Our collections are saturated. We need interesting models and runs of older discontinued classics. Especially bring back the P220, P226, and P229 .22 LR uppers, updated for optics.
A very exciting evolution but I don’t love the FDE/Coyote color- wish it was offered in Black, legion gray or another color. Hopefully the slide alone will be available through the Sig parts website at some point to build my own (like I did several other variants).
