Description
The Sig Sauer P365-380 is built around the idea that effective concealed carry depends on a pistol that disappears on the body, and the magazine is part of that equation. This flush-fit factory replacement is designed specifically for the P365 chambered in .380 ACP — not the standard 9mm P365 variants — and it will not interchange with them. That distinction matters when ordering a spare.
The flush fit means the baseplate sits level with the bottom of the grip frame rather than extending past it. That keeps the overall package as compact as the pistol’s design intends, with no protrusion to snag on a holster or print through clothing. The trade-off against an extended magazine is capacity, but the P365-380 platform prioritizes profile over round count, and this magazine is built to that philosophy.
Sig Sauer builds the body from steel, which resists the deformation that can cause feeding inconsistencies over time. The follower is polymer, a pairing that reduces friction against the steel body during feeding. The spring is designed to maintain consistent tension across the full 10-round load, so the last round feeds with the same reliability as the first.
Because this is a factory magazine — made by the same manufacturer to the same specifications as what shipped with the pistol — fit and function are not variables. Feed lip geometry, body dimensions, and spring rate all match the tolerances the P365-380 was engineered around. For a carry pistol where magazine reliability is non-negotiable, that consistency is the practical reason to choose a factory part over anything else.
