Magpul recently expanded its AMAG line to include the SIG P365. Touting all the same features and enhancements made to their P320 line of AMAG products, the AMAG 17 SG9 – SIG P365 is just the first offering in Magpul’s P365-platform product lineup.
This new magazine gives you 17 rounds of 9mm (that’s +1 if you’re keeping count). Additionally, it includes grip extensions for the X/XL and Standard grip lengths, as well as a standard floor plate for the Macro, so it fits most P365 grip module sizes without looking out of place.
We should also point out that it’s obtainable at a fraction of the cost of many other P365 mags on the market.

Magpul AMAG magazines were designed to work with guns that just wouldn’t allow for the dimensional thickness of polymer construction. To that end, the AMAG 17 SG9 for P365 gives you a stainless-steel body incorporating Magpul’s standard proven features, like a high-vis, controlled-tilt follower, stainless-steel spring, and flared floorplate that’s easily removed to allow you to clean and maintain your magazines.
This AMAG also has a paint-pen dot matrix for markings, and its spine features capacity-indicator windows starting at five (5) rounds and increasing in 1-round increments.
As noted above, because the P365 offers so many variants, Magpul also includes grip extensions for the X/XL and Standard grip lengths, plus a floor plate for the Macro, which allow the AMAG to be used comfortably in all P365 pistols.
