ProMag Bersa Thunder 380 Magazine .380 ACP Blued Steel 10/rd

The ProMag Bersa Thunder 380 Magazine .380 ACP Blued Steel 10-round is a purpose-built extended magazine for the Bersa Thunder 380, 383A, Series 95, and Firestorm 380 pistols. Constructed from heat-treated blued steel with a proprietary DuPont Zytel polymer follower and base plate, this magazine combines proven metallurgy with modern polymer engineering to deliver reliable feeding and longevity in a compact defensive platform.

The 10-round capacity extends your operational magazine supply without adding excessive length, a key consideration for shooters who prioritize concealability alongside magazine retention. The chrome-silicon wire spring is heat-treated for consistent tension and reliable chambering across thousands of cycles. The blued-steel body resists corrosion in field conditions, while the molded polymer components provide controlled feeding and reduce wear on the magazine well during insertion and removal. Made in the USA, this magazine meets the design requirements of the .380 ACP cartridge and the specific geometry of Bersa's compact frame platform.

This magazine is suited for defensive carry, range training, and duty applications where the Thunder 380's lightweight, low-recoil profile makes it accessible to shooters of varying experience levels. The extended 10-round configuration provides sufficient capacity for self-defense scenarios while maintaining the compact form factor of the host pistol. Critical compatibility note: this magazine is not suitable for the Bersa 383 or 383DA models—verify your specific pistol variant before purchase.

The .380 ACP cartridge has established itself as a pragmatic choice for deep concealment and backup carry roles where recoil management and shot placement matter more than raw velocity. ProMag magazines for the Bersa line maintain the same domestic manufacturing and material standards that support the broader tactical magazine market, ensuring you can rotate multiple magazines through training cycles with confidence in consistent performance.
