PDW MAGAZINE "L" CLAMP
The magazine clamp is a tried and true method for speeding a reload either proactively or reactively. Most of the magazine clamps on the market set the magazines side by side. This is fine for a carbine, but impossible to use effectively with a magazine contained in the weapon's pistol grip. The Israelis solved this years ago with a clamp designed to carry an extra magazine at "L-shaped" configuration for the UZI SMG.
We took the concept and applied it to the Glock PDW. This worked great with the 31 round ETS Magazines, and needs some fitting with the OEM Glock 33 Round magazines. With the ETS magazines the hold is firm and holds up under extended firing. A perfect fit and match.
The technique is to carry the reload to the rear. As you can see in the images, the spare magazine rides closely up against the Shockwave adapter/brace. On the reload, the operator presses the magazine release button, extracts the magazine and with a turn of the wrist, and without the need to go to the belt, has another reload in the weapon.
