Installed the third kit in the new stainless 75b. This install didn't go as smoothly as the other two. Punched out the trigger return roll pin, and the roll pin punch was stuck solidly in the frame hole and would not come out. I was able to pull the roll pin out, but the 3/32 punch was stuck really good. I went to the store and bought another punch to bang it out from the other side, but that only broke the new punch. The original punch sheared off later, with about about 3/4" of the shaft remaining, because I was twisting the original punch trying to remove it.
Next step was the local gunsmith since I'm lacking the tools to remove this stuck punch. Anyway, $65 later the gunsmith was finally able to remove it by using a drill bit to relieve the pressure and soaking it in lubricant.
I have absolutely no idea why the punch got stuck that bad in that bleep hole in the first place. A 30 minute trigger spring kit install turned into a several hour nightmare.
I finally finished the install after this headache. I didn't put a the pull gauge on it, but' it's close to the others. A very good bonding experience.
I do this because when I started with CZ's early in I had to learn a lot quickly and I paid more because I didn't have the right information.
Here is what I learned:
1. Modifying these guns is expensive but the potential gains are incredible. When complete these guns are by far the best handguns I own.
2. Always use a floating trigger pin. You shouldn't reuse the flared pin
3. Buy a starter pin to remove the factory flare. Normal punches aren't as effective and you risk damaging parts.
4. Replace the firing pin retaining pin with a hardened one.
5. Use an O-ring to dry fire.
I'm sure there are more.
When I started modifying my CZ's I didn't buy a starter punch and didn't buy a floating trigger pin. As soon as I sat down to disassemble the gun I struggled with the pin. I realized instantly that I couldn't use it again. Guess what. I had to go buy one and pay shipping costs a second time and wait a few days for it to arrive. I also picked up a starter punch. That cost me more money and more hassle. It was a learning experience.
I quoted my comment from earlier.
I guess you learned your lesson (I hope).
I'm not trying to gloat... Only trying to prove a point that the rest of us have been trying to articulate and you seem adamant to argue.
It looks like any cost savings you experienced are out the window and you still don't have the floating trigger pins or a starter punch to do this properly.
I know exactly what you went through. I did the exact same thing myself. As I mentioned in my post I now have a starter punch and out floating trigger pins on all my guns. I suggest you do the same.
Hopefully you haven't enlarged the hole large enough that a floating trigger pin still fits and won't walk itself out. You can use some red loctite in order to try and keep it in there if that's the case.
Also, please stop promoting this kit unless you also provide the disclaimer that you'll need to buy a starter punch and floating pin from someone else. That completes this kit in my opinion and you are proof that is the case. I wouldn't want someone else to experience what you just did. (though I appreciate your honesty and posting about it)
