I was teaching a TN Handgun Permit Course last weekend when the unthinkable happened; a Glock malfunction.  I was using a very old 1st or 2nd generation magazine that I had not tested in a long time.  Bottom line is that I got 2 stove pipes in about 10 shots.

I can’t stress this enough.  If you are going to carry a gun, you need to MAKE SURE IT RUNS!!  Don’t think it runs.  Take the time to run your carry rig with the ammo you are going to use on the range for extensive testing.  Had that mag been in a CCW situation it would have been bad news.
