Springfield XD Tactical dual action spring

[JJ1911]

Was wondering if anyone had any experience with dual action springs in a Springfield XD Tactical.

is the link to the springs in question.

Sounds like a nice idea. My only concern is how well they are tested before release. How long will they last? Does the slide still make it all the way back, just at a lower speed? Or is it designed to stop short of impact?

thanks civilsnake those are very good questions and perhaps I will just shoot them an email. I came across their site almost by accident and my main concern was that it would affect reliable ejection. If for instance the slide comes back with less force, will it travel far enough to properly eject a spent case and feed another round.
