Description
This is a genuine BERSA factory magazine engineered specifically for the Thunder 45 Ultra-Compact pistol. It's built from quality steel components using the same manufacturing standards and materials that come with new Bersa firearms, so you're getting the same durability and fit you'd expect from an original equipment magazine.
The 7-round capacity matches the pistol's typical load, making it perfect as a spare mag for range sessions or as a backup for everyday carry. The magazine features a removable polymer floor plate and follower for easy disassembly during cleaning and maintenance. A stainless steel spring works inside to keep consistent tension across the magazine's lifespan, and the black matte finish resists glare without adding weight.
Because this is an OEM part made by Bersa rather than an aftermarket copy, it's been tested to meet the manufacturer's specifications for fit and feeding. If you own a Thunder 45 UC Pro or the standard Thunder 45 Ultra-Compact, having an extra magazine on hand means less downtime between shooting sessions and adds a practical layer of redundancy for self-defense applications.

Frequently Asked Questions
Will this magazine work with other BERSA models?
This magazine is specifically designed for the Thunder 45 Ultra-Compact and is also compatible with the TPR45C, Thunder 45 UC Pro, and Mini Firestorm 45. It won't fit BERSA pistols in other calibers like 9mm or .380 ACP. Always verify compatibility with your specific model before purchasing.
Is this a genuine BERSA factory magazine?
Yes, this is an official OEM magazine manufactured by BERSA to their original specifications. It uses the same quality materials and manufacturing process as the magazines that come with new BERSA Thunder pistols, ensuring proper fit and reliable feeding.
Can I take this magazine apart for cleaning?
Absolutely. The magazine features a removable polymer floor plate that makes disassembly straightforward for cleaning and inspection. This is one of the practical design features that makes field maintenance easier during a long range session or after storage.
What grain weight ammo should I use with this magazine?
This magazine is designed to handle standard .45 ACP loads. The Thunder 45 UC platform has shown best reliability with 150-grain ammunition, so if you experience any feeding issues, try switching to lighter loads before troubleshooting the magazine itself.
How many of these magazines do I need?
Most carry setups benefit from having at least two magazines on hand—one in the pistol and one on your person as a reload. For range use, three or more magazines reduce downtime between shooting strings and let you practice mag changes.
