As discussed before....MAC's test was very "scientific" and repeatable. The value of such a test by MAC is very questionable, as shown by all the other amateurs who have also done their own testing whether you love or hate the VP9, please don't base it on a non-scientific amateur test like the one that was done by MAC.
The last most extensive testing of handguns done world wide was the US Department of Homeland Security Testing. Millions of dollars spent on testing all done scientifically. Example, dust chambers with small, medium and heavy particles over set times ect. Another test was to simply shoot all the guns to destruction, all random production samples. The results are classified and not available to non-LE / Military. The results were a join contact between HK and Sig. Over 40000 guns purchased initially with follow-on contracts.
Now this will come as a shock to many, Glock failed the testing. Only HK and Sig passed, Joint Contract Awarded as a result. I love Glocks and they have a reputation for passing harsh testing, but they failed. But many other brands failed miserably proving that only certain brands of firearms are truly "Service Grade". Take a look around the world at handguns used by SF. You will almost always see only 3 brands: Sig, HK and Glock. This is because when you perform proper scientific trials (often spending millions of dollars on) they are most often the only ones that pass, with the odd exception.
When someone does not have access to these testing results or have the knowledge base connected to them, they then rely on the internet videos to form their opinions.
Internet videos are good entertainment though !
