The manual safeties do not contribute to flawless high performance.
Nor have manual safeties been proven a detractor to flawless high performance. Your point?
BTW guys with Glocks have numerous times defeated guys using guns with manual safeties.
And guys (girls, too) with Glocks have numerous times been defeated by guys (girls, too) using guns
with manual safeties. Your point?
Manual safeties always have the potential for hindering flawless high performance
Statistics on just often this occurs? Can we prove that someone who errs in competition -- or on the street -- would have performed flawlessly if using a gun without a manual safety? I submit that the root problem is training and practice, not equipment.
And Guns without manual safeties have the
potential -- there are statistics to back this up -- for increased instances of negligent discharge.
Why would you want to have an unnecessary piece of equipment that increases the possibility of making an error?
Sigh. You haven't been paying attention, lo these past decades, have you? Features on firearms aren't always there because that's what the end-user desires, requires or actually needs. Law enforcement bean-counters, risk management specialists, insurance companies, extremely stupid elected officials (see U.S. Congress and the legislative bodies in states such as California, Massachusetts, New York, Illinois, Colorado, et al) and in particular, those litigators who spawn like vermin, have all conspired to bring us collectively to this point.
And while we all wish we were such master gunfighters in the mold of Gabe Suarez, Rob Pincus, "Test Pilot" and others (sorry, too numerous to mention), most of us probably SHOULD be carrying handguns with manual safety devices. If you are one of the high-speed guys that doesn't feel you need a safety on your pistol, more power to you.
(By the way, my employer gave me a couple S&W M&Ps -- without safeties. We used to issue pistols with decocking safeties, but alas the increase in NDs and the decrease in budget funds still sees us with our polymer perfection ...)
