CZ527 and SAFETY

If you have a CZ527 - please read this!

Alright, for those of you who have read my posts you know I like CZ's - I have 2 and the second most accurate factory gun I have is a CZ 527 in .223. But beware!

Last weekend my son and I were at the farm burning off a few brush piles that needed to be gone before any rabits decided to make them nurseries. While napping in the sun we saw a groundhog and I decided that the first whistle pig of the season was due. I loaded and put on the safety, applied the "set" trigger, and once I was almost on the hog, released the safety and the gun went off. Yes, you read that correctly, the gun went off when the safety was released. This was a gun that I was happy with the trigger out of the box and never adjusted.

My 16 year olds comment was "good thing that was pointed in a safe direction - I guess that is why you tell me never to trust a safety". Man was he right.

I unloaded the gun and while waiting for the fire to burn down played with the gun and found I could make it go off with the set trigger on and removing the safety 50% of the time. I decided to do nothing more until I had it home and the instructions in fromt of me. I cleaned the trigger with lighter fluid and there was no change. I then increased the pull weight of the set trigger so that you had to work the safety 5 times to get it to go off when it shouldn't.

My lesson - never ever trust the set trigger, safety combination on these guns. From now on, if I need to have the safety on, the set trigger will not be used, and if I apply the set trigger and then the safety, I will remove the "set" prior to removing the safety.

If you have one of these guns - please be very careful. We are all safe (even the groundhog)because follow the safety rules - you need to be aware of this weekness.
 
This is quite typical for a set trigger gun. Just the vibration of turning the safety off might sometime release the sear if the set trigger is extremely light. Lots of folks "set" the trigger while on target with the safety off............This is how I handle all my rifles with set triggers. Certainly you should never handle the rifle with the trigger in the set position. Should the safety be inadvertently deactivated, you have a potential AD in your hands.
