Considerations & Trade-offs
- This is a 17-round magazine, so it adds capacity but also extends beyond the compact footprint of the P365 platform.
- The stainless-steel body with polymer sub-components may be a different fit and feel than the factory magazine setup, so it is worth confirming compatibility with your specific P365 configuration.
- The flared floorplate is removable for cleaning and routine maintenance, which is useful, but it also means the magazine is designed with serviceability in mind rather than being a sealed, no-maintenance component.
- Capacity-indicator windows start at five rounds and continue in one-round increments, which helps with verification but adds visual complexity to the magazine body.
