Question for those who carry sidecar/spare mag with extension

Do you guys carry your extended magazine in your mag holder/sidecar or do you you keep it loaded in your CCW?The reason I ask is I see people who carry a regular magazine and one with an extension and say that they dont actually load the mag in the firearm when they carry it; only in the sidecar. I just got a +3 Hyve extension and have plans for a Tier1 Agis slim.Wouldn’t it make more sense to have the extra capacity loaded should you actually have to use your CCW? Or is this based more off of sheer concealment? via /r/CCW https://ift.tt/3hFn8R3
