Amend2 S300 Hybrid Grip Module for Sig P320 9mm - Compatible with P365 Magazines, Durable Polymer Black

The Amend2 S300 Hybrid Grip Module for Sig P320 gives you real versatility in a single platform. This grip module bridges two weapon systems—it accepts Sig Sauer P320 style fire control units and slides while letting you run P365 style magazines. That means you can build a compact, concealable carry gun that transforms into a full-size duty setup in seconds, all without buying multiple frames or dealing with compatibility headaches.

The engineering here is straightforward: a durable polymer frame with a full-size accessory rail for lights and lasers, paired with P320 slide compatibility that opens up the full ecosystem of optics and aftermarket support. Whether you're running a subcompact, compact, or full-size slide, the S300 handles it. Magazine options include Sig P365 10, 12, and 15-round variants, giving you flexibility for carry profiles and mission requirements. Because it uses P320 slides, you're not locked into compact optics—you can mount full-size optics for duty or precision work.

This is the kind of thoughtful design that appeals to shooters who value adaptability. You get holster compatibility across standard P320 rigs, no need to invest in a new duty holster when your gun changes roles. The polymer construction is built to last, backed by Amend2's lifetime warranty, so you're not betting on durability.
