I received the trigger upgrade and polishing kit yesterday, and today I followed the instruction video successfully. Getting the first pin out was the hardest part, and I admit, at one point I looked down at the bench full of parts and thought to myself "what the %&^ have I done?", but I now have a very nice trigger! Thanks MCARBO, I couldn’t have done it without that great video.
I didn’t see many posts about PO7s, so thought I would share. I was pretty disappointed with the trigger when I got my new CZ, but it is very nice now. First trigger job I have ever done.
