FYI -- I discovered something a little disturbing tonight while cleaning my CZ 527 Carbine. With the trigger in the set position, all it took was a moderate slap to the side of the stock to release the firing pin. I was able to do this repeatedly -- close the bolt, set the trigger, moderately slap the side of the stock on top of the pistol grip checkering, and the sear would break and the firing pin would slam home.

Handle with care once the trigger is set.
 
My brother built one of those BP rifle kits once that had a set trigger option. I rarely used it, though. Once set, the trigger could be pulled using a single strand of human hair (we tried it.) Nice, but you had to be careful when placing your finger anywhere near the trigger after it had been set. You could easily fire the rifle without meaning to...
 
When you begin to measure trigger pull in ounces, common sense safety precautions become even more important. The trigger should not be set unless you are ready to squeeze one off (the gun that is :))

I only use mine from the bench. The trigger is good enough in the regular mode for the shooting that I do.
 
Things got much worse this morning at the range. The first time I went to set the trigger, I pushed the trigger forward and the gun fired as soon as I released the trigger (that'll get your attention! :eek:). From that point on, the trigger would not stay set, it just dropped the firing pin every time I tried to set it.

The standard trigger worked fine, it was just the set trigger that was causing problems. I'm going to pull the action out of the stock and adjust on the trigger screws to see if I can cure the problem. Otherwise, I'll be sending it to CZ for repair.

Anyone else had a problem like this? I've only had this rifle a few months and it's only been fired a few hundred times. Hopefully, it just needs a little tweaking of the trigger screws.

I had this problem on a 550 Varmint. Adjust the set adjustment heavier and it'll cure your problem. They are adjustable ya know.
 
You just have it set too light. Mine is probably about 1# and frankly I don't like using it. My friend shot my carbine for the first time a couple weeks ago and had a slight ND as his finger was resting on the trigger while at a 45 degree angle.:eek: I was about 2' away. Good thing he knows to keep it pointing downrange at least.

You won't have to send it back to CZ. The trigger is fully adjustable.
 
I have a Remington 721 that I adjusted the trigger so light it would release the firing pin upon closing the bolt. That is a true "fully adjustable trigger". :D Never took it too the range like that though. Just adjust that trigger so its a bit heavier and to your liking.
 
Will do. I'll be pulling it apart tonight.

You just have it set too light.

I've never touched the trigger screws. This is how it came from the factory. It's always been very light in set mode, but it's worked fine until today. I'll definitely tinker with the set trigger screw and rig up a homemade trigger scale to test it.

Thanks.
 
I adjusted the set trigger screw on my 527 and it appears to be working reliably again. I turned the screw counter-clockwise to increase the set trigger weight.

Anyone with a CZ rifle be aware that the set trigger can cause an AD if the adjustment screw works it way to being too light. Always make sure you've got the muzzle pointed in a safe direction when you set the trigger.
 
My hunting rifles have set triggers.

Both my 1917 Mauser 98 sporter,

and also my Sharps 1874 Business Rifle.

Set triggers on hunting rifles are just fine - assuming you have the discipline to keep your booger picker off the bang switch until the sights are on Bambi. Millions of double set triggers, Canjars, Keplingers, and other similar triggers have been doing just fine thumping wildlife since the former were installed on muzzleloaders 100+ years ago.

It sounds like the CZ in question is in need of a simple adjustment. Use a dab of Blue Loc-Tite or even Red to keep it from working out of adjustment again.
 
Yet again, Gewehr posts beautiful pictures of his personal firearms that I've never seen before--I'm jealous, but mmmmm, that eye candy......:D

Thanks for the warning, RNB. Though I personally prefer the "old-style" double trigger setup posted by Gewehr, the fact that CZ's can do it mechanically is nifty, IMO. That screw setup is kinda alarming, but maybe it unscrewed while you were whopping the stock?

EDIT: Not to hijack, but G98, I'm curious....is that set trigger an "always functioning" one on that sharps, or do you have to fiddle with the one, and it makes the other a hairtrigger?
