I'm taking my daughters to school this morning and I throw on my G29SF on my primary side, with a 15 round G20 magazine worn on my belt, offside. I'm feeling pretty well armed with this setup, as usual. I got home a few minutes ago, had a hankerin' for .45 ACP so I went to swap the 29 out for my 21 and 30. As I'm unloading the G29 magazine (standard with a Pearce +2 ext.), I notice the rounds POURING OUT. The follower had bound up at the bottom, no spring pressure at all to push rounds 2-12 into the gun. This could have been a one-shot gunfight if I had needed the pistol. Fortunately, years ago I started carrying a spare magazine. Each and every time. No exceptions. I feel naked without at least one. Today's potential FUBAR would have been remedied with a fast reload to the G20 magazine. I'm the idiot for not checking my kit before rolling out this morning. So, I implore all of you out there who CCW, PLEASE always carry a spare. Even if it's in a pocket, mag pouch, jacket etc. You might not need 150 rounds at an ATM robbery, but as we've all heard 1000 times, most failures are mag related. Get a new one in there QUICK! I almost met Murphy this morning, I'm glad I was (at least partially) prepared.
