I have tried several glocks, including the 19. They are OK. Very reliable, but the again, many others are as well. The thing I just cannot get over is the lack of a safety. I don't care how careful you are, sooner or later an inexperienced person will pick up that gun. When you pull the trigger on a revolver, you know something is happening--the cylinder is turning and the hammer is coming back. Likewise with a DA/SA auto--there is a long deliberate pull and the hammer moves. With a striker pistol, you have none of that. The trigger is a fine place for a safety device, but the dumbest place in the world for THE safety on a semi-auto. An NG can kill just a easily as a deliberate shot and a pistol should be designed to minimize that possibility (within reason of course). Safety-less Strikers might be fine for range games, but I just cant buy into the concept for a gun that will likely at some time be lying on a table or dresser.
That's why I put a NY1 trigger AND a 3.5lb disconnector on mine. It gives a longer more revolver like pull. The NY1 just by itself is awful.
