Only a few people understand modern combat pistolcraft like Larry Vickers, and he knows that even the smallest things can ruin your day. One of these small things are your OEM magazine's floor plate because they are typically undersized and offer no drop protection. The Vickers Tactical floorplate solves these issues by giving you a flared floor plate with grooves for positive finger purchase. The elements will never get in your way again! May it be mud, ice, or sand, just hook the floor plate under your belt and extract. The molded dimples make for easy marking and numbering, as well. These Vickers Tactical Floor Plates are only compatible with Glock magazine calibers 9x19, .40, .357 SIG, .45 GAP. The floor plates are NOT compatible with early Gen 1 non-metal lined magazines. However, they are compatible with Gen 5 models 17, 19, 19X, 26, 34 & 45.
