The HKS 940 Double Stack mag loader is a simple mechanical solution for anyone who shoots .40 S&W pistols and gets tired of fighting spring tension while hand-loading magazines. If you've ever pinched a finger or dinged feed lips forcing rounds into a tightly-wound double stack magazine, this loader takes the fight out of range prep. It's the kind of no-fuss accessory that disappears into your gear bag but shows up when it matters—letting you spend your time at the range shooting, not battling stubborn springs in the parking lot.
Loading is straightforward: slide the HKS 940 over your magazine, grip both the loader and mag firmly, then use the ribbed thumb lever to compress the spring while you feed rounds into the mag. The design relieves spring pressure as you work, so loading the last few rounds—when springs are at peak resistance—doesn't require a vice or brute force. A slot or adjustable stop in the loader's base keeps your magazine stable during the process, so you're not wrestling with it one-handed.
Built from black plastic, the HKS 940 is lightweight and durable enough for regular range use. Double stack magazines have earned their reputation for reliable feeding and capacity, but they also come with stiff springs—and that's where a good loader earns its place in your shooting kit. This is straightforward gear: no batteries, no moving parts to break, just mechanical advantage where you actually need it.

Frequently Asked Questions
Will this loader work with my .40 S&W double stack magazines?
Yes—the HKS 940 is designed specifically for .40 S&W double stack magazines. It accommodates the wider, higher-capacity design of double stack mags and uses a stabilizing slot or adjustable stop to keep the magazine steady while you load.
Does this prevent damage to my magazine feed lips?
Yes. By mechanically relieving spring pressure as you insert rounds, the HKS 940 eliminates the need to force rounds into the mag by hand, which is the primary cause of feed lip dings and damage.
How does the spring relief lever work?
The ribbed thumb lever compresses the magazine spring as you depress it, relieving pressure on each round you're inserting. This is especially helpful when loading the final rounds, when spring tension is at its peak and hand-loading becomes difficult.
