ProMag Magazine Glock 42 380 ACP 32-Round Drum Polymer Black

The ProMag Glock 42 .380 ACP 32-round drum magazine is built for shooters who want to maximize rounds downrange without frequent reloads. This compact-framed .380 pistol magazine holds significantly more ammunition than factory alternatives, making it a practical choice for range sessions, training, or shooters who simply prefer extended capacity in their Glock 42. The drum design feeds reliably from a US-manufactured platform backed by proven quality control.

ProMag drums are engineered with heat-treated chrome silicon wire springs—the same precision components that define their reputation across the firearms accessory market. Every magazine that ships undergoes multiple assembly checkpoints to ensure consistent feeding and durability. The rugged black polymer construction handles the wear and tear of heavy use, and the easy-loading design means less hand fatigue when you're prepping for a full day at the range or in the field.

Because this is a 32-round drum for the Glock 42's .380 ACP chambering, capacity far exceeds what you'll find in single-stack magazines—useful if you shoot frequently or train in high-round-count sessions. The drum profile works well for range carbines and home-defense setups where you want reliable, extended firepower without breaking budget. Made entirely in the USA, it's backed by a lifetime guarantee against manufacturer defects, so you can trust it to perform year after year.
