Overview & First Impressions
Compact pistol lights are a compromise exercise, and Fenix split the compromise into two SKUs. The GL06 fits Glock and Picatinny rails; the GL06-365 reshapes the rail interface for the SIG P365 and P365XL family, where grip length leaves no room for a bulky housing. Both run 600 lumens and a 459-foot beam from the same ARB-L16-700UP cell, so the choice is fitment, not performance. If you have spent an evening comparing rail adapters, this comparison already saved you one.
Materials & Construction
Aluminium housings, quick-release lever latches, and a patented replaceable rail key system that lets one body serve several pistols. The lever latch locks with positive resistance and survives recoil without walk-off, which is where cheap rail lights fail first. Both variants charge over USB, and the small cell swaps out if you would rather rotate spares. Build consistency across Fenix flashlights weapon lights has been solid, and these are no exception.
Design & Details
The ambidextrous switch runs momentary or constant-on from either side with one finger, and strobe is available for disorientation without adding a second control you might fumble. The 600-lumen output is deliberately chosen: enough to identify at indoor distances, not so much that white walls bounce you blind. The GL06-365 keeps the bezel inside the trigger guard silhouette of the P365, which matters for holstering and for concealment.
Real-World Use
On a Glock, the GL06 rides duty-style and clears most holsters cut for lights. On a P365, the -365 variant is simply the only shape that makes sense; adapting the standard body works but adds overhang you feel when drawing. Recoil tracking held zero on both test guns over a few hundred rounds. As a house-light beside your EDC knives, either body doubles as a compact handheld with the rail key removed, which is a genuinely underrated fallback.
Ownership Notes
Charge monthly whether or not you shot, because small cells self-discharge faster than the 21700 monsters. Check the rail key screw after range sessions; thread-locker holds, but vibration is vibration. Clean the lens with the same cloth as your scope glass, not your shirt. If you rotate between two pistols, buy spare rail keys rather than a second light. Store with the switch accessible, not buried in a dump pouch. Mount it next to the EDC flashlight you already carry and the glovebox pairing is complete.
Who Is This For?
Buy the GL06 if your pistol wears a Glock or 1913 rail and you want proven quick-release fitment. Buy the GL06-365 if the P365 or P365XL is your daily gun and you refuse to carry a light longer than the grip. Skip both if you need laser integration, because these are pure beam lights; the Nitecore flashlights rail line covers that niche. Either way, EdcMall stocks both variants at the same output tier.
Final Verdict
Fenix answered the compact weapon-light question by machining two answers instead of one bad compromise. Same output, same cell, same switch logic, two fitments that each actually fit. EdcMall carries both versions, and the pricing gap is small enough that fitment should decide it. For SIG shooters the GL06-365 is close to the only compact light worth bolting on; for everyone else the standard GL06 is the safe pick.
