After thinking about a couple of .40 S&W JHP, very, very high energy rounds in a magazine (for my Glock 23, w/standard barrel),I decided to make a change. After removing the 1st round in the 40 S&W magazine, the next two rounds were .357SIG. The rest of the rounds were 40 S&W,FMJ. If you can say AAaWWWww Sshhooeey, I sure did.
I don't like confessing to something like this, but shit happens. After 55 years of firearms familiarity, sometimes we f___-up, when multi-tasking. Conclusion; don't have your Glock .357SIG & .40S&W ammo and magazines on the same table and be BSing/Lolly-Gagging around. Like me ,you could do something (non-smart) that could really be "eventful" during a crisis.
The 2nd part of this story is; when I go to the range I always shoot off the cartridges that I have had in a magazine first. I can call this , the Great Escape !
