(178) Tough Under Fire (Phase II): Master Lock versus 5.56mm NATO


LockLab is Fan funded!  Help pay for stuff to review, break and talk trash about, and maybe even give away when we’re done.  Join the Tribe!

My vises are made by Panavise, a U.S. Company.  The one with the wide jaws is the model 350.  The smaller one is the model 301. Both have the 312 Base mount – www.panavise.com



  1. Bill you are the most interesting man in the world. You got me into lockpicking (legally of corse) within the last week. But my first and favorite hobby is firearms so this was a real treat to find this video. I hear guys say that the M193 is harder on plates due to velocity I wonder if it would have fared better. Your agency doesn't have access to m995(I think it's called?) the 5.56mm AP stuff. Thanks for the videos.

  2. Seems to me like they are "Tough Under Fire" for the simple reason that they need to withstand a hammer blow/s. The fact that they can take a bullet is just a convenient byproduct, not any special design by a lock manufacturer against bullets. So they just took the opportunity to advertise on it at zero development cost.

    If I'm not mistaken, and you seem informed enough to know, someone trained to breach a door would shoot the actual door where the lock is, not at the lock itself. Correct?

  3. So what does this tell us? It tell us that NATO should have never switched away from the 7.62 round because it carries much greater energy to the target.

  4. Velocity is the key here, double the mass of the original bullet at the same velocity, gives twice the kinetic energy delivered to the target. Double the velocity of the original bullet and you deliver four times as much kinetic energy.

  5. No Iron Man suit unfortunately… but I WAS wearing one of our assault kits (ballistic kevlar…) and a face shield – hence the muffled audio.

  6. Pretty daring doing it at such close range without apparent cover from possible ricochet!  Or did you have an Iron Man suit on?

  7. Try that with a 12ga and call me back… You won't have an intact lock anymore. They make special breaching rounds for 12ga for blasting hinges off doors and killing locks. I figured you guys had those. 

  8. Colt. Most LE orgs now don't opt for the "fun switch" as it increases the liability insurance rates and raises the chance for hitting innocent bystanders.

  9. Pardon.!!!! only joking Bill. My ears are shot now and wife knows I listen no more. My lad wants to do as his Dad does when picking and he will thanks to what you sent him

  10. I happen to have one, but hardly think it worthwhile. The .50 is REALLY loud and would wake up the whole neighborhood. Easier (and quieter) to drive my car through the front door.
