What Did the 5 Fingers Say to the Mag? SLAP!

Loading mags is a total drag. Makes me want to SLAP …
And it seems I’m not alone! Whether you’ve got a little arthritis or just think loading mags is boring, Unorthodox Designs has your back … or palm, we guess? The company has just released its SLAP Loader for Sig Sauer P320 9mm magazines. (They also have one for Glock 9mm/40S&W.) The SLAP (Single Load and Press) Loader was created specifically to address issues with common popular loaders by, quite literally, turning the problem upside down. 
Rather than sliding over the top of the magazine and relying on the user’s grip strength, the SLAP Loader provides a stable platform to insert a magazine, allowing rounds to be fed into the loading ramp with minimal effort. A simple press down on the magazine effectively loads a single round into the magazine. Releasing the magazine completes the process and readies the loader for the next round, resulting in a fast and efficient loading process that can be done with a single hand.
The SLAP Loader features a durable glass nylon injection-molded design and non-slip base for reliable use on nearly any surface. It is currently compatible with factory and aftermarket metal-body P320 9mm magazines. A round-stripping notch is built into the side of the loader to facilitate fast unloading of magazines when required.
Both the Sig Sauer P320 9mm and Glock 9mm/40S&W SLAP Loaders are available exclusively online at GunMag Warehouse here. (Rick James and Charlie Murphy not included.)
