ADCO ST5 Super Thumb ST5 Double Stack Mag Loader - Black Polymer, Compatible with .380 ACP Glock 42, Bersa Thunder Plus, Beretta 83/84, Browning BDA

Loading magazines by hand is tedious and can be brutal on your thumbs, especially when you're cycling through a stack of double-stack .380 ACP mags at the range or during practice sessions. The ADCO ST5 Super Thumb is a mechanical mag loader designed to take the strain out of manually pressing rounds into compact pistol magazines. If you run a Glock 42, Bersa Thunder Plus, Beretta 83/84, or Browning BDA, this loader speeds up your prep work and saves your hands from fatigue when you're loading multiple mags.

The ST5 features a black polymer construction that's lightweight and durable enough for regular range use. Its straightforward mechanical design works with most double-stack .380 ACP magazines, making it a practical addition to your shooting kit whether you're prepping for a match, a training session, or just building a supply of loaded mags for carry or backup. It's the kind of simple tool that doesn't sound essential until you've loaded your tenth magazine by hand and realize how much easier this makes the job.

Magazine loaders are a smart accessory for anyone who shoots regularly and wants to reduce repetitive strain and speed up the reload process. The ST5 isn't fancy, but it does one job well—and does it across several popular .380 platforms.
