Short video that shows what happens when a suppressor isn't properly secured before shooting. Back story is the barrel's threads had a burr and while the suppressor felt it was fully engaged and secure it was actually binding against the burr. No damage to either unit - once the burr was taken care of the everything was checked, reattached, and was good to go.

The shooting stance looks very uncomfortable!

Yeah it wasn't the most comfortable stance - this was all part of an HK Instructor course and they kept on grilling the "aggressive stance" and while it does great while controlling your weapon, especially on full auto, it lacks in the comfort dept. Somwhere there's a happy medium between comfort and solid shooting platform.

look highly unstable to me like you gonna fall backwards any second from recoil. why dont people just shoot normal instead of trying to be all tacticool?

While leaning that far forward does help in full-auto, it's too much for a handgun. You are actually going to slow yourself down shooting like that.

Do a google search and watch some of the top USPSA shooters, and note their stance. I remember reading an interview with Brian Enos about how in the 80s, guys like he and Rob Leatham would experiment with anything and everything to do with shooting faster / more accurately / better. Not just "feels faster" or "looked faster" but against a timer to measure what was actually faster.

Agreed. I took this course eight years ago and have kept the fundamentals of the stance - albeit in a much less aggressive posture.

For another guy, it had nothing to do with being "tacticool" it was just another method the instructors were teaching at the time. Put the TTP away and use it when needed.

I don't get how the suppressor fell off. Someone explain that to me.

Unless it was shot excessively before hand (vdo editing) without it being checked for tightness.

And how does an HK barrel get a burr on it? The threading doesn't start 1/4". It kind of has its own thread protector

Something is not right...

obviously they do, but if a burr occurs on a MK23 you just shoot it again, this clears the burr and the pistol can then operate as designed.

My MK23 is flawless, as designed. Bigger this time for clarity.

Neither does my personal Mark 23 - but there's a big difference between caring fo your own $2k pistol and running a demo unit that gets beaten, bashed, used and abused.

I don't get it, are you using it as a hammer? Even if you dropped the Mark 23 on its muzzle, it won't get a burr. It might get dented (highly doubtful) , maybe even eggout but get a burr, and then have it disappear when you shoot it... There is something more that your not telling us.

Agreed, mine is my daily driver and I completely lost count of how many rounds are down the tube - I think I'd be embarrassed to say anyway. Granted, I've yet to drop it or throw it down a gravel driveway though.
