Further Information and CZ-52 Links
We have been doing this for quite a while. We have an FFL and do gunsmithing and other custom precision machining work.
Links
Below are some CZ-52 pages that we find useful and interesting.
Lists like there are hard to maintain — if you find any links that don't work, or if you have any suggestions of what we might add, please let us know!
For the maximum benefit from our firing pin / trigger conversion, we recommend you also install a heavy Wolff recoil spring, 16.5 pound or heavier, available at gunsprings.com.
