Thanks for the Tips guys
Hold Open Installed and functioning just dandy
Very Slightly put a bevel on the entry side of the Spring
Held the Hold Open in a padded vise by the end ( 3rd hand )
Held the Spring in position and gave it a squeeze with a pair of pliers
Slid in smoothly
I did have to relieve ( bend slightly ) the Spring as it overpowered the Mag Follower
As Vlim noted more than likely luck
