When you need a spare magazine for your Bersa Thunder 40, there's really no substitute for the factory original. This is a genuine OEM mag from Bersa, built to the exact same tolerances and specifications as the magazine that came with your gun. That means reliable feeding, a consistent fit, and no guesswork about whether some aftermarket part is going to cause issues at the worst possible time.
The body is constructed of steel with a matte black finish that keeps things low-profile and matches the look of the pistol. Inside, a high-tensile steel spring works alongside an injection-molded polymer follower to keep rounds moving smoothly and consistently through the feed path. The feed lips are precision-machined, which is what you want for reliable chambering round after round. A removable polymer floor plate rounds things out, making disassembly for cleaning straightforward.
Capacity is 13 rounds of .40 S&W, and this mag is compatible with the Thunder 40 and Thunder 40 Pro models. Worth noting: it does not fit the Ultra Compact variants, so double-check your model before ordering. Also, like most new factory magazines, the spring may feel stiff right out of the box. That's normal and it loosens up with use.
Whether you're stocking up for range days, keeping a spare in your range bag, or want a reliable backup magazine for your carry setup, this is the right magazine to grab.
This magazine is designed to fit the Bersa Thunder 40 and Thunder 40 Pro. It does not fit or function with Thunder 40 Ultra Compact models, so make sure you have the standard or Pro version before ordering.
This is a genuine OEM factory magazine made by Bersa. It's built to the same specifications and tolerances as the magazine that originally shipped with the gun, which means you can expect a proper fit and reliable function without any compatibility concerns.
Nope, that's completely normal for a new factory magazine. The high-tensile steel spring may be tight right out of the box and can make loading to full capacity feel like a workout at first. After some loading and unloading cycles it will loosen up and break in just fine.
Yes, the polymer floor plate is removable, which lets you fully disassemble the magazine for cleaning and maintenance. Keeping your magazines clean is one of the easiest ways to ensure reliable feeding over time.
That's a personal call, but having at least two or three total magazines makes range sessions much more efficient since you're not constantly reloading a single mag. A spare also gives you a backup in case one magazine gets damaged or develops a feeding issue down the road.
