Overview

Built for the Hellcat and Hellcat RDP, this 15-round 9mm magazine adds capacity while keeping the profile compact. Its stainless steel construction, polymer follower, and numbered witness holes provide a straightforward, practical setup for range use or as a spare carried in the field. The extended base gives additional gripping area and matches the Adaptive Grip Texture of the pistol frame for a more integrated feel. At only .28" taller than the 13-round extended magazine, it offers extra capacity with minimal added height.

Considerations & Trade-offs

  • This is a 15-round magazine, so it adds capacity but also increases the amount of magazine protrusion compared with lower-capacity options.
  • The extension provides extra gripping area, but that added length may change how the pistol carries or fits in some setups.
  • It is specified for HELLCAT and HELLCAT RDP models in 9mm, so compatibility is limited to those listed firearm models.
  • The magazine uses a steel/polymer construction, which offers a mixed-material design rather than an all-metal build.
