I have gone with the Shield in 9MM for my EDC as I like the capacity of 8+1 and I purchased an additional 8 rd magazine. The IWB holster holds the spare mag and I have not had any issues with CCW. I can ride in the car and not be uncomfortable. I keep the 7 rd mag in the console. I figure if I am in a SD situation I would be at my car anyway. The training that I have done centers around shot placement and tactical mag changes. I have not heard of any situation either in which someone ran out of ammo, unless they were firing warning shots!
