To be perfectly honest, when I decided to make a mold of one of my CZ so I could cast a model of it so I could have holster and grips made for it, I did not realize that the liquid would literally get into ever itty bitty crack or hole. I had the big obvious ones sealed with tape, but that was not good enough, OH no not even remotely good enough
Skip to the finish and I had to take the pistol apart down to the last screw and spring. After I had used a couple dental picks to get the molding material out enough that I could finally take the weapon apart I realized that I only have a couple drift punches and nothing small, I went to Home Depot bought one of every single punch that I thought would reasonably be used to take the pins out of any pistol. So now I have about 8 or 9 punches, in both drift and punch and the biggest set of Miniature driver tools I could find. Like Jewelers screw drivers but in both Metric and US along with nut drivers, Star drivers and every other screw or nut you can find on pistols and rifles. Cost about well less than a 100.00 total and a couple I will most never ever use including some of the miniature screw drivers, but better safe than sorry. I also suggest you invest in some dental picks, I get mine at the flea market since who cares if they are used as long as they can still get things out of tight and tiny places. Trust me when I tell you this. Get a punch with a really, really small diameter, cause if you ever make the mistake of taking the Safety apart to clean it. You are not only going to need that skinny punch (To go through the holes in the safety and the tiny little piece of metal that wholes the spring in place but a large plastic bag to to put it back together in.
Actually taking a Thorazine or Ritalin or at least a Valium before you tried putting those three thing back together and get them to fit back on. Anything with caffeine in it would be a bad idea. so no soda's or coffee or chocolate while you are working on the thing.
Do NOT remove the thing that you are using to hold all the pieces together with until there is absolutely no room left between the frame of the pistol and the safety, and good luck with that.
The guy that came up with that design, was a sadist.
