In the context of various plausible emergency scenarios in which a handgun might be needed, who would rather have a 33rd mag over a spare 17rd mag? Do you guys consider the 33s as mostly for range / game use, or do you think they should be held in high regard as an emergency spare? Side questions: Does anyone keep a 33rd mag in their HD gun? Does anyone carry a 33rder as a spare (on- or off-body, and under any circumstance)? Thanks.
