No, the follower is different. He has been working on a new design for a Para follower but AFAIK, there is nothing available yet. On a different note, it has been my experience that S_I tubes will work in a Para frame without modifying anything. The S_I tubes sit a bit lower so a weak spring will show up sooner but if your feed ramp geometry is OK, they feed fine.

I have no problems running stock unaltered STI magazines along with the unaltered magazine release in my Para.
What caliber Para did the STI magazines fit into? This is the 1911 page so I am guessing 40?
