Promag Bersa Thndr 380acp 10rd Nckl

The Promag Bersa Thunder 380 ACP 10-round nickel magazine is a reliable extended-capacity feed solution for Bersa Thunder 380, Firestorm 380, and compatible 383A/Series 95 pistols. If you carry a .380 ACP for everyday defense or backup, running a single factory magazine leaves you vulnerable—this 10-rounder doubles your on-hand capacity and gives you genuine staying power without swapping guns or fumbling for reloads.

Built from heat-treated nickel-plated steel, the magazine body resists corrosion and spring fatigue over thousands of cycles. The follower and base-plate are molded from DuPont Zytel, a tough engineering polymer that handles the friction and pressure of repeated loading and ejection without cracking or wearing. That combination of materials is proven in aftermarket magazines across the industry—it's not exotic, but it works.

The extended length holds all 10 rounds reliably and seats firmly in your Bersa's magwell. Whether you're stocking a truck gun, building out a backup carry setup, or just want more ammunition at the ready during practice, this magazine fills a real gap in the .380 ACP ecosystem, where factory options are often limited.
