Help with firing pin issue

[crash83]

Working on a friends SP01 , installing a Cajun Gun Works ultra light kit.
During assembly , no matter what , the plunger will not capture the firing pin.
Plunger is orientated in the correct position, as is the firing pin.
I've done these multiple times without issue.
Anyone had this issue?
