Stepped out of my comfort zone and picked up a X-grade CZ 82 to play with.
Step 1: Ordered a spring kit and tore it down, replaced anything that looked too worn and successfully put it back together.
Step 2: I am a hobby woodworker and made some cherry grips for it.
Step 3: I stripped the finish and phosphate coating and using Mark Lee Express blue took it through 8 cycles (until no rust formed when applying the bluing agent). Overall I am pleased with this first attempt and although far from perfect, looks much better that where it started and will remain in my collection.
