Default Tabs Missing

With the factory spring, the slide hits that buttress, and the slide is stopped. When that stop occurs, the spring is not yet fully compressed. Since the spring is not fully compressed, and the slide has been stopped, there is no forced being applied to those tabs. All of the energy has been absorbed by that buttress.

With the aftermarket spring, the slide never reaches that buttress, because the spring becomes fully compressed before the slide hits the buttress. In this case, the compression of the spring IS what is stopping the movement of the slide. And since the spring is stopping the slide, the energy from the slide is transferred through the spring/guide rod and into whatever is behind the guide rod, which happens to be those tabs. In essence, the slide is slamming into those tabs each time a round is fired.

The tabs were not designed to take the force of the slide travel, because the slide was designed to stop on that U-shaped slide-stop.
Just noticed that in these pictures the "tabs" are completely gone. Maybe the intent was to show them gone but the focus is on the primary buttress.
