But think store prices overcharge so shopping around. I want 4 total. Currently 2 are being used for protection ammo which leaves a 3rd empty. I want to get 3 more mags to make it 4 for the range. I was thinking of maybe going 10 total and load them up before the range. Anyway, I will be shopping around but any place that sells them at the lowest let me know. Glock19 GEN4 gun.
