Here's a strange one: A friend has a CZ 75B made in '96. His recoil spring guide is metal. I have a CZ 75B made in '98. This guide is some kind of plastic(polymer?). What's the deal, and should I get a metal guide? No functional probs, I just wonder why the change in materials. Also, anybody try Microlon Gunjuice and, if so, notice any improvement in accuracy after treating bore as the ads claim? Thanks!

Have two 75b's made in 96 and one had metal and the other
had plastic..Wondered about it and called CZ-USA and asked..
Was told that the switch to plastic was to provide a buffer effect
along with it's normal function of recoil spring guide rod..
Thought it was a good idea and bought one,plastic,to replace the metal..Whole bunches of rounds later,no problems...

metal/plastic spring guide
Just for an experiment, I borrowed friend's metal recoil guide and switched w/my plastic one: had 2 FTF and one FTE in first 25 rounds! Replaced metal guide with my stock plastic guide...went through about 250 rounds that morning with ZERO malfunctions.
Now my friend wants the plastic type.
BTW, at the urging of gunstore owner where I bought the CZ, I ordered a recoil spring from Wolff gunsprings at standard factory weight rating. Zero malfunctions. Good products! Also ordered increased strength magazine springs -- factory springs seemed anemic. New ones from Wolff are stiffer and, again, totally realiable feeding.
