Happy New Year guys!
Yes, I worked with CCF for a little while and developed a CCF specific guide rod system to help with the frame battering problem with the .40 S&W. I looked around my shop and I found one. basically it was a polymer rod with an extra thick head at the back, a soft nylon bumper and flat wire recoil spring wound specifically for the system. This allowed the recoil guide rod and bumper to take about 50% of the load from impact due to the "almost" short stroke. It worked, and frames no longer suffered the battering using my rod. CCF folded, and I learned a lesson. Anyway, I stopped making them since there really were so few out there.
Now there's a few tricks that can help. First, in order to use the polymer rod you need to grind down a molding flaw, a "dimple" that is raised in the frame where the guide rod head sits. the second issue they had was locking blocks failing. They were machined with incorrect angles and dimensions causing the failures. I showed CCF what the locking blocks need to look like, and then they ran with my block to another vendor. Anyway, the best solution here was to take the OEM locking block, cut off the bridge and hand fit it to the frame with emery paper after rounding the edges to fit. Bombproof.
Thanks, I rarely visit the forum but Happy and Healthy New Year to all! Look for a fat discount coupon to members soon! I'll post in vendor forum after I tackle my webmaster....
later, Billy
