SIG P365 Holsters

Custom Kydex SIG Sauer P365 Holsters

No pistol on our bench has branched like this one. The P365 was never replaced by a successor — it split, and grip length and slide length now move independently of each other, with compensators showing up on some branches and not others.

The upshot is that “P365 holster” is not one answer. We hold nine separate patterns across the family, more than for any other pistol we build, and the only wrong move is guessing which one you need.

Patterns tooled
One per branch of the family, because no two of them wrap the same at the muzzle and the grip.

The figure that stayed still while everything around it changed. The XL and Fuse run longer.

Comp

Changes everything
A compensator adds material exactly where a shell would close, so comped guns are tooled apart.

Cut after you order, which is the only way to keep nine live patterns without holding stock.

Which P365 Are You Actually Holding?

These are the nine lines in our model selector, and what each one means for the shell. The two dimensions that matter are how far the slide runs forward and whether anything is bolted to the end of it.

Selector lineWhat sets it apartPick it if
P365The original micro-compact. Shortest slide and shortest grip in the family.Yours has no suffix on the slide
P365 XLLonger slide and longer grip than the base gun.You have the XL as it left the factory
P365 XL (No Spectre Comp)The same XL without the compensator fitted.Your XL has a plain muzzle
P365 XMacroThe larger grip module, carrying the most rounds of the family.Yours is a standard X-Macro
P365 XMacro CompX-Macro with the compensator, which extends the profile forward.You can see porting at the muzzle
P365 XMacro IcarusX-Macro built on the Icarus grip module.Your grip module is branded Icarus
P365 FuseThe longer-slide member of the family.Yours is badged Fuse
P365 AXG Legion Gen 1Metal grip module, first generation.You have the earlier AXG Legion
P365 AXG Legion Gen 2Second-generation metal grip module.You have the later AXG Legion

Two things settle almost every case: is there porting or a comp visible at the muzzle, and is the grip module polymer or metal? Answer those and the line is usually obvious. Send a side-on photo if it is not, and we will identify it before anything gets cut.

Cross-Fit

What Carries Across the P365 Family

Because so much of this family swaps parts, people assume the shells swap too. Grip modules and magazines travel; holsters mostly do not.

FirearmShares this shell?What to order
P365 with a 12 or 15-round extended magazineYesExtra length runs downward, clear of every surface the shell contacts. Only your spare pouch has to match.
P365 with an aftermarket rail adapterNoRecover and Tactical Dev style adapters bolt on under the dust cover, which is exactly where the shell closes.
P365 with a manual safetyAsk usThe lever sits on the frame above the trigger. Tell us and we will confirm clearance before pressing.
P365 XL or FuseNoLonger slides that run past the end of a base P365 shell and leave the muzzle unsupported.
P365 X-MacroNoA different grip module entirely, so the shell meets the frame in a different place.
SIG P320 in any sizeNoA separate platform on a separate chassis. Nothing about the two is interchangeable.

The reliable test: anything that changes the outline from the trigger guard forward changes the holster. Anything below the grip line almost never does.

Choose the matching line, tell us how you want it mounted, and that variant gets its own cut on the bench.

Carry Style

Carrying a Micro-Compact SIG

The P365 sold as many units as it did because it disappears. The build should not undo that.

P365 Appendix IWB

What the pistol was designed around. Narrow slide, short grip, and a claw to roll it inward.

P365 OWB

The one to reach for on range days, when burying a short grip below your belt line stops being clever.

P365 Sidecar

Pistol and spare on one chassis, which a ten-round flush magazine makes an easy case for.

P365 Mag Carriers

Flush, twelve and fifteen-round magazines are three different lengths. Tell us which you carry.
Lights & Optics

Lights on a P365 Are a Two-Part Question

Green Kydex SIG Sauer P365 holster on soft loop belt attachments

Look through our light list and you will find two entries that exist for this pistol alone: an Olight Baldr Mini with a Recover rail, and the same light with a Tactical Dev rail. That tells you what you need to know — on much of this family the light does not bolt to the pistol, it bolts to an adapter that bolts to the pistol, and the adapter is part of the shape we press:

Optics. Most of this family is optic-ready from the factory, and our P365 shells run a sight channel cut to clear a shielded micro dot. Tell us the optic and any rail adapter together when you order — those two decisions interact, and getting them into the same press is the difference between a clean draw and a shell that scrapes.

Popular P365 Configurations

Every one of these is available across all nine variants. Set the exact line, your hand and your clip on the product page.

Triton Series IWB Holster

$50

The straightforward starting point for a micro-compact — single clip, adjustable retention, and no more bulk than the pistol needs.

Hades Series IWB Sidecar

$90

Carries the spare alongside the pistol on one platform, which is the honest answer to a flush magazine that holds ten.

Double Magazine Pouch

$60

Two spares moulded to the exact magazine you run, because the flush, twelve and fifteen-round bodies are all different lengths.

Compare

P365 vs P365 XL vs P365 X-Macro

The three variants people actually cross-shop. Note that barrel length is not what separates the base gun from the X-Macro — the grip is.

P365P365 XLP365 X-Macro
Flush capacity10+112+117+1
Barrel length3.1 in3.7 in3.1 in
Grip lengthShortest of the threeLonger than the base gunLongest of the three
Comped version in our selectorNot listedYes, and an uncomped line tooYes, listed separately
Separate holster pattern?YesYesYes

Pick by grip, not by barrel. The base gun and the X-Macro share a 3.1 inch barrel and feel completely different in the hand and on the belt, because everything that changed is below the slide. The XL splits the difference by growing in both directions. Whichever you own, order the line that names it — and if you are still deciding between platforms, the SIG Sauer holster page covers the P320 and P226 side of the range.

Why Neptune

Nine Patterns Is the Point

A shelf-stock maker cannot carry nine versions of one pistol, so it carries two or three and calls the rest close enough. Cutting to order removes that constraint entirely:

FAQ

SIG P365 Holster Questions

Nine, which is more than we tool for any other pistol. The list runs from the original P365 through the XL and the XL without a Spectre comp, the X-Macro in standard, Comp and Icarus forms, the Fuse, and both generations of the AXG Legion. Each is a separate pattern rather than a shared shell with extra clearance, because grip length, slide length and muzzle hardware all vary independently across the family.
Yes, and it is the single most common ordering mistake on this platform. A comp extends the pistol forward into the space the Kydex was going to occupy, so a comped gun simply will not seat in an uncomped pattern. Our selector reflects that by listing the two forms separately, including an explicit line for an XL without the Spectre comp. Check the muzzle before you order.
Usually only with a rail adapter, and that adapter becomes part of the holster. Our light list carries the Olight Baldr Mini twice for this reason, once with a Recover rail and once with a Tactical Dev rail, both specified for the P365 and XL. The Streamlight TLR-7 Sub and the clamp-on TLR-6 are the other common answers. Whichever route you take, tell us the exact combination so it goes into the same press as the pistol.
No. The XL grew in both directions — longer slide and longer grip — so it runs past the end of a base P365 shell and the muzzle finishes outside the holster with nothing supporting it. Retention is taken forward of the trigger guard, and that geometry no longer lines up. The XL has its own line in the selector, as does the version without a Spectre comp.
They do not. Extended magazines grow downward, past the bottom of the grip and clear of every surface the Kydex contacts, so one holster covers all three. The spare carrier is where it bites: flush, twelve and fifteen-round bodies each measure differently, and a moulded pouch only fits the one it was pressed for. Name yours at checkout and that is the one we cut.
Bigger in the grip, not in the slide. The X-Macro keeps the same 3.1 inch barrel as the original P365 and adds a substantially larger grip module carrying seventeen rounds, which is why it feels like a different class of pistol while measuring the same up front. For holster purposes that means the shell meets the frame in a different place, so the two do not interchange despite the shared slide length.
Both, and both generations of the AXG Legion are tooled separately. The AXG uses a metal grip module rather than polymer, which changes the frame profile where the shell wraps, and the Fuse sits at the longer-slide end of the family. Neither shares a pattern with the base gun. Select the exact line at checkout and we press to that variant.
The Triton Series IWB starts at $50, a double magazine pouch is $60 and the Hades sidecar carrying pistol and spare together is $90. Pressing a light or a rail adapter into the shell does not change what it costs. Builds take ten to fourteen business days because nothing is pre-made, which with nine live variants is precisely why we can offer all of them. Should SIG branch again into something we have yet to tool, that first one needs a new mold and will take longer than the usual window.
