I just traded for a CZ10, it appears to have an after market spring/guide rod. It's appears to be stainless steel with a silver spring. I would like to start out with the oem set up but for the life of me it's very difficult to find an oem set up. It appear the spring should be blue and a plastic rod.
Any help in pointing me in the right direction would help.
PS: I have the same delema with a P75 PCR. Yes it's been a good trading week.
