The more I read about this the more I think I'll use the Nyclads mainly for the reduced recoil for my wife. I'm not sure if it will be any real benefit for overpentration but I'll just have to be careful. Another issue is that the new Nyclads don't really have a track record yet but after reading Greg Ellifritz's research on stopping power of the common pistol rounds I am less concerned. Thanks to all who posted here .This is an excellent site for getting good advice from serious folks.
Just remember, you'll mainly get opinions parroted from gun magazines, when you ask about terminal performance on an internet forum. Most have never done, or even watched any actual testing, and recommend whatever brand their favorite writer has been bribed to tout.
Over-penetration as a problem, was largely invented by the the frangible ammunition makers, and their paid writers. The more real problem, was
under-penetration. Focusing on the
possibility of unintended victims from rounds
over-penetrating targets, while ignoring the majority of rounds
missed those targets, and those that hit, weren't penetrating enough to stop the threat, caused more rounds to be fired, and got cops
and civilians killed.
Thankfully, law enforcement learned from their mistakes, and largely stopped taking advice from unqualified gunwriters with financial agendas, and discredited mythical "studies". Unfortunately, the lure of magic bullets, and "documented one shot stops", still feeds the Walter Mitty's minds, and sells expensive ammo to the public, that doesn't work.
