No, they certainly are not Sigs. Sigs are DA/SA, hammer fired... re: archaic design.
A lot of people complain about the trigger, but I don't understand why. It has an audible and tactile reset, it has a consistent pull, consistent weight, and consistent travel. Very easy to learn imo. I take up the slack, feel the wall, take up the firmer 1/8" of slack, and bang it goes, every time.
I work on malfunction drills, but have never had one irl.
The empty space behind the mag isn't there because they ran out of polymer when they made your gun. It's there for your thumb to tug on the mag to ensure that it is inserted properly, and it's there to help you rip the mag out during a double feed malfunction.
IMO, everything about the g19 is top shelf, and as all glocks function the same, they are all top shelf.
Archaic design, that is funny.
Do not get me wrong, I like Glocks now, but the triggers are terrible.
