I think there is some debate for likely circumstance between department procedure and joe blows just wanting some protection. If you're carrying for duty you may have to engage people holed up and hell bent on going to the very end, potential hostage etc etc. You don't get the option to just disengage. Id assume most civilians are just using it as a tool to break contact as engaging in a sustained gunfight is going to bring quite a bit of scrutiny if that isn't a part of your job. I'm not a lawyer but we've seen people have caliber/equipment/style of weapon utilized in prosecution justly or not. I'm also not saying it would happen but there's a world where a jury of our "peers" could see someone going out of their way to add extra rounds and skew that into looking for a fight for something that likely wont make a ton of difference for the most common semi automatic carry guns today.Back to the topic of capacity. If the gun has the ability to bring an extra round into a fight, why would you not want that round?
My department procedure - insert full magazine. Send slide forward. Remove magazine. Add one round. Insert magazine. Holster weapon.
The Glock 19 already holds 15 rounds. I have two spare magazines with me.
But I’m going to carry that one extra round, because nobody here can predict exactly how the gun fight is going to go down. And when you’re in a gun fight, more ammo is better than less.
This is not an endorsement for or against but I could see why someone wouldn't.
