SIG Sauer P365 SAS “Agency Vault” 9mm — Law-Enforcement Allocation, Micro-Compact, 10+1 Capacity
This P365 SAS comes from SIG Sauer’s exclusive Agency Vault law-enforcement allocation, making it a rarely seen civilian opportunity.

The Agency Vault program sets aside production for police and government contracts; this pistol was part of that run, reflected by its “W365-9-SAS” part number and serialized stainless chassis. Availability on the civilian market is extremely limited and typically confined to aftermarket channels.
SAS (Sig Anti-Snag) engineering delivers a de-horned Nitron-finished slide, machined flush slide catch lever, and tapered controls that draw effortlessly from concealed positions. The proprietary FT Bullseye sight sits level with the slide, using tritium and fiber-optic elements to present a bright, centered dot for day- or night-time aiming without the height of traditional posts.
A carbon-steel, target-crowned 3.1-inch barrel teams with SIG’s striker-fired action for reliable, repeatable accuracy. This later SAS variant retains the standard un-ported barrel and slide, preserving velocity while minimizing blast for close-quarters carry.
The micro-compact polymer grip module features aggressive stippling for confident control, while the stainless steel fire-control unit is removable, allowing future grip or size changes without a gunsmith.
