Product Description

The Magpul AMAG 17 SG9 Stainless Steel 17-Round Magazine (MPN: MAG1486-SST) is a high-capacity, duty-grade aftermarket magazine engineered specifically for SIG Sauer P365 9x19mm handgun platforms. Expanding Magpul’s renown alloy magazine lineup into the micro-compact realm, the AMAG 17 SG9 delivers exceptional structural strength, corrosion resistance, and flawless feeding performance in a high-density 17-round body.

Precision-formed from heavy-gauge stainless steel, the MAG1486-SST features a corrosion-resistant passivated finish that stands up to heavy sweat exposure and moisture during everyday carry (EDC). The magazine tube is engineered with sub-thousandth interior tolerances to minimize stack friction, paired with a high-visibility anti-tilt polymer follower and a stainless steel spring to guarantee positive feeding across wide-ranging 9mm defensive ammunition profiles.

Designed for multi-grip versatility, the AMAG 17 SG9 includes interchangeable grip sleeves that allow seamless aesthetic and contour integration with standard P365, P365X, P365XL, and P365-XMACRO frame modules. Featuring painted dot-matrix capacity indicators along the magazine body and a tool-less, flared polymer floorplate for swift mag changes, the Magpul AMAG 17 SG9 represents a top-tier capacity upgrade for SIG P365 owners.

Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct fit for SIG Sauer P365, P365X, P365XL, P365-XMACRO, and aftermarket modules (e.g., Wilson Combat P365 frames) chambered in 9x19mm. Includes modular base sleeve spacers to provide a flush fit across different frame grip lengths.

1. Perform a complete firearm safety check: drop the existing magazine, lock the slide rearward, and visually/physically inspect the chamber to verify zero live rounds are present.
2. Select the appropriate grip sleeve spacer included with the MAG1486-SST that corresponds to your specific P365 frame length (P365/P365X vs. P365XL vs. XMACRO).
3. Slide the chosen grip spacer down over the stainless steel magazine tube until it seats firmly flush against the flared floorplate.
4. Load 17 rounds of 9x19mm ammunition into the magazine, observing the painted dot-matrix witness holes along the spine to track round count.
5. Insert the loaded magazine firmly into the P365 grip module until the magazine catch clicks positively into place.
6. Perform a tactile tug check on the baseplate to confirm full catch lockup before chambering a round.
