Life keeps changing my range plans. That is why I keep 48 1911 mags loaded and stored in a 30cal ammo can so that when an opportunity to go to the range presents itself, I need only get in my truck and go. Additionally, I spend my range time shooting instead of repeatedly reloading the same 3 or 4 mags.
If these SARCO mags do function properly and are durable, I will fill another 30 cal can with them to keep in my other truck.
