WaPo:Tim Kaine's claim the Las Vegas shooter was only stopped because he lacked a silencer

[JoeStuckInOH]

5. Nope. Silencers take WAY more abuse than that.

"Silencers heat up by 7 degrees per shot. After one magazine the silencer would have been glowing red hot and on the verge of failure. With the next magazine, the silencer would have failed (exploded) and disabled the weapon and possibly the shooter."

I've personally done mag dumps using full auto and takes way more than one mag to make it glow and two to pop it. At your stated "7 degrees per shot" ... that's only +210 degrees for one 30 round magazine. General rule of thumb in the welding shop is something faintly starts to glow red around 1000F. Even assuming this is the celcius scale we're talking about, you don't get a dull red glow until about 550 degrees Celsius. So it would take about 3 magazines before a suppressor was red enough to take notice.


This particular video start to show the faint glow (in daylight) after the 4th magazine with the glowing more evident after the 5th magazine. Since it's daylight outside, the beginning of the glow would probably be seen a magazine-sooner if indoors. Looks like he shoots through about 11 magazines (330 rounds) before things stopped working well.
