4th Gen Glock 17 - Guide Rod Spring Assembly
2010-11-21 · There is a new guide rod spring assembly for the 4th gen Glock 17 that does not have a beveled edge in the slide for the guide rod spring assembly. It is called an '02-1' spring assembly. I don't know what is actually stamped on the spring because I don't have one yet. When I get mine I'll post a picture of the new and old springs all together.
