There were issues with the Hellcats. Also many of the 1911 9s and definitely everybody except
@SimonRL had issues with their prodigys. Right here on this forum there are examples of issues with various Saints. Hex optics ? Anyone who buys one of those ends up wishing they hadn't. There are some issues with guns made by any manufacturer. SA doesn't have this issue any more often than most other brands. It's not like a Taurus for chrissakes.
The drop safe thing with the Sigs was immediately addressed and corrected. All the other lawsuits, most of which are female cops, are negligent discharges masquerading as a Sig problem. Feel free to show me an example of a Sig firing without the trigger being pressed otherwise it's dogpile on the rabbit.
That said, not many SA strikers have issues. Unless you count the numerous complaints about hard to press mag release buttons on XD 45s. I wouldn't hesitate to buy an Echelon if I needed another 9mm carry gun. The VIS thing is pretty cool. It seems like SA is trying to be innovative with their latest offerings. Besides, their CS is exceptional.
