Thank you. That helped. I'll try to get the 20lb spring or 20lb rsa. We are somewhat limited in parts availability in germany.

Does anyone have the lb rate of a factory rsa for a Glock 40 gen 4.
Could not find it on google
If not let me know them i will write to Glock directly to try and get the rate.

Thanks for the warm welcome.
