I can't really speak about Gen 3s, cause I've never owned any. I've shot a few and never liked any of them. Personally, I don't know how anyone can love any traditional DA (as in DA/SA) gun?! How many revolvers could anybody sell if the first shot was always double the effort as the rest - you would be laughed out the door.

That trigger system is dead, regardless of what the gun is made from. There are aftermarket aluminum frames for glocks. Don't blame the frame material, blame the trigger.

I've never had the opportunity to shoot a DAO gen3. I'd jump at the chance if it came along.
