Magpul Introduces Cost-Effective Premium Magazine for SIG P365 Platform

Magpul has expanded their Advanced MAGazine (AMAG) lineup to include support for the popular SIG P365 series. The new AMAG 17 SG9 – SIG P365 magazine represents the first offering in what appears to be a broader P365 accessory strategy from the company. This magazine delivers an impressive 17-round capacity of 9mm ammunition (with room for an additional round when chambered).

What sets this magazine apart is its versatility across the entire P365 family. The package includes grip extensions designed specifically for both X/XL and Standard grip lengths, along with a dedicated floor plate that integrates seamlessly with the Macro variant. This thoughtful design ensures the magazine looks and functions appropriately regardless of which P365 model you carry.

Perhaps most notably, Magpul has positioned this premium magazine at a significantly lower price point compared to competing extended magazines for the P365 platform. With an MSRP of just $34.95, shooters can decide for themselves if this represents a substantial value in the market.

True to Magpul's reputation for quality, the AMAG 17 SG9 features a corrosion-resistant stainless-steel body complemented by their signature design elements. These include a high-visibility follower with controlled-tilt function, durable stainless-steel spring, and a flared floorplate that can be easily removed for maintenance.

For practical field use, the magazine incorporates capacity-indicator windows along the spine beginning at five rounds and continuing in single-round increments. A paint-pen dot matrix allows for personalized identification of individual magazines.
