Guide rod replacement for G20
I have a Gen II Glock 20 that has a guide rod spring assembly that is not captured. It's a real pain to reinstall - I had to make a simple tool to install it.
The question is: are the guide rod assemblies for the Glock 20 and Glock 21 the same? From what I have seen on parts lists the 20 and 21 are listed at the same time and probably the same for power and size.
I have a spare unused Glock 21 guide rod spring assembly I could use in the Glock 20.
