I’ve heard people give reasons why they may or may not carry a spare. I have always taken to the line of thought I’m not likely to need the additional ammo but I might have a malfunction which dictates it’s need. This is a perfect example of a magazine failure. I’ve had two of these last year or two one on a 70 Series magazine today on a newer production magazine. I’ve had other magazine failure or malfunctions but thought I’d share this one since it’s fresh in my mind. I went to the range shot a few magazines through my commander went home to clean it reloaded after to put it back in the holster and this happened.
