earthshine402 Posted March 17, 2015 Share Posted March 17, 2015 What is the "proper" way to test that a firing pin block is functional on a Tanfoglio or CZ which has one? Link to comment Share on other sites More sharing options...
bikerburgess Posted March 17, 2015 Share Posted March 17, 2015 The only way I can think of is to cock the hammer and then push the firing pin in with a punch of some sort. Link to comment Share on other sites More sharing options...
rowdyb Posted March 17, 2015 Share Posted March 17, 2015 what i've also seen done is rack the slide back and lock it. take punch and press on end of firing pin. if the other end goes out past breech face, fail. (cause i've failed this test at a different match) but i can not attest to the accuracy or repeatability of this method. it's just what happened in my case. i'd really like to know as well.

bikerburgess Posted March 17, 2015 Share Posted March 17, 2015 That wouldn't work on a Tanfoglio because the block is lowered to disengage it Link to comment Share on other sites More sharing options...

The tanfo is backwards to your glock or M&P. Up is blocking the pin. Link to comment Share on other sites More sharing options...
rowdyb Posted March 17, 2015 Share Posted March 17, 2015 how i described is how they did it on my cz75b. i'd like to know what is "the way" then to test? whether it is a cz or tangfo Link to comment Share on other sites More sharing options...

In that, I mean it drops the FPB to allow the FP to move forward. This is how the tanfo works. The sear holds the FPB in the up position until the trigger is pulled and drops the block. So if you lock the slide back, you should be able to move the FP. You should not be able to move the pin if you just cock the hammer. Link to comment Share on other sites More sharing options...
rowdyb Posted March 18, 2015 Share Posted March 18, 2015 iirc, the fpb on my 75b is lifed by an arm in the sear package. disengaging it from blocking the firing pin. spring 59 in the diagram pushed the fpb part 58 down onto the slot in the top of the firing pin. to disengage it the fpb has to be lifted by arm part 14. http://s9.photobucket.com/user/falcn12/media/Firearms/CZ%20P07/CZ75B_PartsDiagram.jpg.html Link to comment Share on other sites More sharing options...
