HKS Magazine Speedloaders
Magloaders — Thumb Savers

Single Stack vs. Double Stack (aka Staggered): This is a characteristic of the gun. For the gun, if there exists a magazine where the cartridges line up in a staggered formation, then the gun is considered double stack. Some double stack magazines limit the capacity to 10-rounds or less by forcing the cartridges into a straight stack by pinching in the sides--these are still considered double stack. Single stack magazines are only slightly thicker than one cartridge, while double stack magazines are generally 1-1/2 to twice as thick as one cartridge. If you are not certain, contact the manufacturer of the gun. If there is a dimple along any part of the length of the magazine, or the magazine is otherwise thickened, it will likely not work with the single-stack loaders above, despite the manufacturer classifying the magazine as single-stack.

• If a specific version of a gun is not listed (such as compact), the magloader might not work.
• If the gun manufacturer has changed the gun or magazine in recent years, or it is a newer model, it is possible the above listed speedloader for that gun may not work--check with the gun manufacturer.
• If the magazine has a fat base plate or a pinky extension, the above listed speedloader for your gun may not fit properly.
• If the magazine has an insert or dimple to push the round forward, the speedloader may not work properly.
• 9x19 = 9mm Luger = 9mm Parabellum = 9mm NATO -- different names for the same round, this is the most common 9mm cartridge in the World.
