G21sf recoil spring/rod
 

I have a gen 3 G21sf (along with 5 other Glocks). I noticed when breaking down for cleaning that the rear of the stock guide rod and spring had slipped "down" and out of its notch. Usage is not what I would consider heavy -- approx 3500 rounds over 2 years. Its happening now after a few cycles, not just live fire... Have not had this happen on any other model. Has anyone had this happen, and how did you correct or fix?

perfectly normal, Just make sure during reassembly that you put the RSA in the notch.

Wow, OK...will do. I had not heard of this before. Thx!
