cz 70 firing pin remove/replace
« on: June 25, 2017, 12:14:07 PM »
Next step... Ok, better a dumb-ass question, than a dumb-ass mistake...I am going to order the Harrington firing pin kit, and install it, but need step by step instruction on firing pin removal/replacement so I don't make a dumb-ass mistake and ruin my latest acquisition. I know it's easy, but want to have my hand held while I do it...LOL!!!!  If all goes well, then off to the shop for a new barrel and a reblue job...or maybe cerakote... Then, some nice grips.. Will post photos when done.  THX!!!!

I ordered the Harrington firing pin for my Vzor 70 which I bought from my LGS.

Their gunsmith installed it for me for no charge and even polished the hammer stalk to make the DA pull a little less.

I installed my own though I had to trim some of the firing pin block spring in order for it to work. My decocker still works as it should with no hitting of the firing pin.  I tried it about a dozen times to make sure it was still good.

It's very easy and the Harrington web site has instructions with pictures.

Followed directions, however, the drill bit size that was needed to smooth out the pin chamber was a bit off... After a bit of work, the pin went in, and functioned as it should with the pencil test...also, using the pencil test, the decocker WILL fire the weapon...so.... Off to the shop for a park job...then off to the range. Will post when that happens.
