Luger Steel Lanyard 'Staple'

[sheepherder]

Sorry for the confusion...I'll rephrase...

Does anyone know how the Luger steel 'staple' [lanyard loop] on the back of the gripframe is retained???

Press fit? Interference fit? Peened in place???

Have you ever removed one? How tight was it? Did it pop right off or require major force to remove?

Has one ever been observed loose??? Have you had one fall off???

No special reason why I'm asking. Just a rainy Spring day, looking at Luger blueprints, measuring grips, checking eBay for a front sight...Idle curiosity mostly...

To further clarify...It be this part back here...
