Here is the video fo the PTS Enhanced Pistol Shockplates for Tokyo Marui 1911 and Glock airsoft pistols that should be available now at retailers and dealers. These are specifically designed to reduce shock to the magazine if dropped, helping prolong the life of the magazine. The simple one-piece design made from TPU rubber has just the right hardness to absorb shock whilst being hard enough to avoid tearing if forced or pulled.
