I recently purchased a used CZ Scorpion Evo 3 S1 at a local shop. There is a bit of play between the upper and lower parts of the pistol. I did some searching around the web and it seems that it’s normal but quite annoying to me. I took it apart to see what I could come up with. Below is what I came up with.
Disclaimer: I am not a gunsmith. I will not be responsible for any damages/injuries should anyone decide to attempt this. Do at your own risk.
I took a small thin piece of aluminum, rolled it to size and stuck it in the hole where the pin goes to take up the slack. Feels better now.
If anyone sees any issue/damage this may cause to the firearm, please let me know.
