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...
