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.
According to Wolff Gunsprings the standard is 17 pound, The 40 is the same as the 20.

The 20 and 40 do use the same exact spring... 17 lbs.
I put a 20 pound spring in my G40, so far I like it.
I put the Wolff non-captured RSA in my G20 with a 20 pound spring and I also tried a 22 pound spring.
For all around use I use the 20 lb. but for Underwood the 22 lb. works well. It's too much for standard (S&B & Blazer) to function every-time.
Thank you. That helped. I'll try to get the 20lb spring or 20lb rsa. We are somewhat limited in parts availability in germany.
