I put about 700 rounds through my new glock pistol and thought I should clean the magazine, so i began to disassemble the floor plate by depressing the little round button on the bottom with a long screwdriver and pulling the floorplate forwards. The little button is now stuck inside the magazine and all i can see is part of the spring when i look through the hole. Does Glock make a tool for magazine disassembley? Has anyone eles had this problem??? Any advice would be very apretiated.
