I'm fairly certain the patent is long expired. Taurus and Para Ordnance both used their own version of the system. I just had to look up what Auto Ordnance is doing these days and it looks like they are using some variation of it. Just remember the term "Series 80" has come to mean has a firing pin safety actuated off the trigger in the same way "Series 70" means it does not have a firing pin safety. The Swartz system is actuated off the grip safety and creates timing nightmares.
The Series 80 system can have an either acceptable or crappy trigger pull from the factory. The old trick to get a good trigger job with one was to use the safety flag from a Colt Gold Cup. I have a couple setup that way and they're triggers are quite nice. I have not idea if that is possible with the copycats of the system.
If you have an aversion to the classic 1911 system then it's your choice not to carry one. Personally owning a safe full of 1911's and having carried and worked on them for years I have absolutely no qualms about the system and consider it no less safe than any other pistol when it is maintained properly.
One incident in recent memory where an officer was killed after dropping his pistol was here in 2002:

In this case it was a SIG P220 that landed on the hammer. It was an older P220 with the spur hammer, but was equipped with a firing pin safety. Just because a gun has a FPS doesn't mean if maintenance has been neglected and it's your time to die bad things won't happen. A properly maintained 1911/2011 dropped in the same fashion wouldn't have gone off. Just sayin.
I owned a Staccato P, sold it, and now have a Staccato C2 en route (the P was just too bulky for what I need). We have about a dozen Staccato's in use at my department right now and I think they're a great pistol for the money. One guy at my department carried a 5" 45 ACP STI 2011 on-duty for a decade or so up until 2018, switched to a 5" 9mm STI, then to a Staccato P, and now has the P and a CS. He and I have gone to a whole bunch of classes together and between his guns I'm sure he's well over the 50,000 round mark with very little issues.
