Plagued with a common issue, the CZ 712 is well known for light strike issues. A simple search engine query results in a considerable amount of references to firing pin protrusion issues. My 2013 CZ 712 (identified by the first two numbers in the serial, i.e. "13XXXXXX) is no exception and has light struck many of my reloads which tend to have a deeper primer seat. This is a major concern for me since I require each of my guns to perform equally as well.
Although there are many of these references, none have actually explained why or how this light strike occurs. Some have noted CZ gunsmiths referencing early, circa 2004 and older models, having Out Of Battery ignition due to a firing pin design flaw. I noted in my online research, that a recommendation of .050 to .060
should be fine but this was on a CZ double gun and is less than my factory protrusion length. Ill need more pin in my situation.
The original, dangerous firing pin is identified by its physical taper and silver/chromed color, while the newer version has a straight, non-tapered shape with a brown coating. If your CZ 712 has the old style firing pin, its advised that you call and schedule a send in for replacement. *
If you have the newer style and are experiencing light strikes, you may need some "tuning" of your bolt body and locking lug. Here is the fix including a description and pictures.
