Purchase the integrated system at a significant savings. Includes both the GTUL for the 9MM/40S&W and Mag Brush. GTUL will work with both standard and extended floorplates, the punch can be used to field strip your Glock or take apart any centerfire pistol magazine except the XDM
* PLEASE READ FOR TEN ROUND CLINTON MAGAZINES *
The technique for these magazines can be slightly different than hi caps. The design makes it difficult to push the reinforcement plate into the mag body more than a quarter of an inch. To start, place GTUL on the mag, then push the punch down and forward of the retaining pin. Squeeze GTUL while keeping downward pressure with the punch. Use the punch and leverage it against the front edge of the retaining pin to slide the floorplate off. I have found some ten round magazines where the punch can be moved side to side and worked down in front of the reinforcement plate. This allows you to disassemble these magazines like a hi cap.
