backstrap

I was struggling with backstraps on my 19 gen4 when I read the manual and realized I never got the long pin. is it in the fired case envelope? or tossed loose in the foam box? Thanks for any info,

This is a set of Glock factory back straps with the pin and installation tool. They came with my Glock 17 brand new and never used. I will ship to the lower 48 states only and I will ship for FREE. I am asking $20 by Cash , Paypal or Money Order. Thanks for looking.
