If he's just referring to the trigger bar safety not resetting on early release 2013 shields.....that was 6 years ago and S&W did a good job with the recall. Post recall and fixed handguns function and are proven reliable at this point. They do not have glaring design flaws and S&W hasn't cut corners on sourcing (unlike Sig). Anyway, a trigger bar safety failure still allows the handgun to function. It would still require the trigger to be pulled to fire, so it's not totally unsafe as long as you aren't a moron.
The P365 on the other hand is a poorly designed handgun that Sig decided to further FUBAR by cost cutting on sourcing of parts. They have a bad design that causes a lot of striker drag, and then they use Indian MIM strikers on top of that. They aren't adequately fixing the problem. And if this failure mode happens and you actually need to rely on your handgun.....well, it's not going to go bang when you need it to. That's a MUCH worse failure mode than what S&W Shields had.
Sig is a garbage company ever since Ron Cohen took the helm. They produce junk. They knowingly cut corners in R&D as well as material and sourcing.
Sig seems to have passed military trials for the new service handgun, while S&W wasn't even an afterthought.
Probably because they didn't have handgun design experts with internet firearm engineering degrees to help them out.
