This 7rd magazine is built specifically for the 383A Series, 95 Thunder, and Firestorm 380 pistols chambered in .380 ACP. It is constructed from heat-treated blued steel with a follower lockplate and a baseplate molded from a proprietary DuPont Zytel-based black polymer. The spring is wound from chrome-silicon wire and heat-treated for strength and reliable feeding—features you want when you depend on each round.

Construction and durability

The combination of heat-treated blued steel body and a DuPont Zytel polymer base ensures balance between durability and weight. Heat-treated chrome-silicon springs resist fatigue and maintain consistent tension, which helps reduce feeding issues over time. The follower lockplate design improves lockup and makes disassembly for maintenance straightforward.

Fit, compatibility, and notes

This magazine is specified for the 383A Series, 95 Thunder, and Firestorm 380 pistols. It is not suitable for the Bersa 383 or 383DA models—confirm model fit before purchasing. Promag is a recognized aftermarket brand; choosing a purpose-built mag avoids feed geometry issues that can arise from generic replacements.

.380 ACP: practical defensive caliber

.380 ACP offers a compact package for deep-conceal pistols and pocket pistols. While ballistics are modest compared with larger calibers, modern defensive ammunition and reliable feeding make .380 ACP a practical choice for users prioritizing concealment and controllability. A dependable 7-round magazine like this one preserves the pistol’s balance and reload ergonomics.

Price and purchasing tips

At $18.99, this magazine provides a cost-effective spare that maintains factory-style materials and spring construction. When buying, verify your pistol model and avoid using it with incompatible frames noted in the product description. Routine inspection of the blued-steel body, polymer baseplate, and spring will extend service life.
