I just bought a s&w shield this gun came with 1 standard magazine and one extended magazine that has the sleave that fits over it. I would like to have 2 more mags to go with it but I want them to all be the same. I feel like the extended magazine defeats the purpose of buying a small gun but if I use the standard mag my third finger hangs off. I have seen some mags with a hook on them to accommodate the third finger but I don't know where to find them. Suggestions please.
