I recently upgraded my G17 Gen 3 recoil spring to a stainless steel one from the glock store. With the shortage on ammo, having none, I have been doing dry fire practice. After about a week or so I had noticed wear on the guide bar of the recoil spring. It appeared the spring dug into the guide bar leaving grooves. After not getting help through email or phone, I decided to just send the recoil spring assembly to glock store with a note. I received an email stating that this was normal wear for the part.
I am not an expert but the only wear I could think would happen is friction from the spring riding on the guide bar. Anyone here know anything about this? Is this normal wear for a stainless recoil spring? The only wear I noticed on an oe recoil spring is from the spring riding on the guide rod.
This experience with gs has led me to stray away from purchasing from them again, regardless if my problem is an issue or not. Their customer support is terrible to say the least, it took over a month to finally to get a response from them and I only got that a week after the received the recoil spring.
