Can't believe you missed this thread? If that's it you need to get out more...
That plastic rod deformation is good to know. I need to go and check some of my 75B's for a plastic rod and see whats what. Also that Cajun Gun Works is a new source for me...out of West Monroe, LA. I've relying on CZ and Angus Hobdell's sight.
I deal with the CZ Custom Shop all the time. They are about a 30 minute ride from me. I went with Cajun Gun Works because it was easier to have it shipped right to my door in just a couple of days, instead of driving across town. I'm headed to the range at first light today to see how it runs. I'm not expecting any issues, but you never know.
What upset me about this was how soft and flimsy the rod was. It is also way too short. The Stainless Steel Rod From Cajun comes flush with the end of the slide. With the plastic OEM rod, I can insert the length of a toothpick into the guide rod bushing before it contacts anything. This allows the spring to bunch up and bow, because there is nothing to support it as it compresses. Along with allowing the rod itself to bend and bow because it is made from material that is too flexible.
And it is also far too small of a diameter which exacerbates the problem . Hence the bowing of the rod from just sitting. Plastic guide rods are no different than plastic anything else. They are OK if manufactured correctly, and are of good design to begin with, (Glock). This one wasn't. Obvious proof of that, is you shouldn't have to start replacing parts in a new pistol before you shoot it, in order to have it function correctly.
