Isn't an issue? Penetration is THE issue with the 5.7, even in SS190 trim... As far as the lethality of the round, countless law enforcement agencies have dropped the weapon system after it has proven ineffective. Everyone wanted this weapon system to live up to all the hype the FN junkies created, but it simply lacks substance. Fired out of either weapon system in any of the commercial or LEO-only loads, the 5.7 lacks the penetration and expansion of standard subgun calibers and lacks the energy of a full blow 5.56 or other rifle caliber... Simply put, it was a really cool looking, really hyped failure.Originally Posted by ministerofdeath
I've followed quite a few of your posts, ministerofdeath, and you absolutely have your terminal ballistic "priorities" bass-ackwards. Energy is great, but ONLY when it compliments adequate penetration. Energy scores a DISTANT second to penetration when ranking performance of defensive ammunition.
I'm not saying this weapon system has no application - if a small PDW with the ability to lay down crazy suppressive fire is required, the P90 fits the bill (and god knows it beats out HK's failed 4.7mm ). In the hands of very skilled operaters (as is the case with the Secret Service), the quality of shooter is going to make up for the weapon system's shortcomings... But at the end of the day, trying to liken the 5.7x28mm to a viable replacement for the 9mm-.45ACP, .223, or any other "real" caliber is a losing proposition - the numbers simply do not add up.
And what a tangent we have taken this thread on... We started out talking about the MSAR and stumbled into the dark, chimeric world of FN and now onto discussion about a cartridge that no MSAR has (or will be) chambered in... A new thread would probably be prudent if you guys wish to discuss all this business in further detail... :beer:
