Not my Tikka! Fired engaging safety

[Tahoe1305]

Out hunting with my son and some friends this weekend. My buddy was borrowing my rifle and he text that after he fed a round in he went to put the safety on and it fired.

I assumed likely user error. When he brought it over later in the day. I loaded another round and very slowly and deliberately pulled the safety back to engage. Boom. Fired again.

Trigger is set to ~2.5lbs (like all my tikkas). Never been an issue before including shooting targets the day before.

I plan to do some googling and tear it apart to see what I can find when we get home. But I’ve had tikkas for the last decade and never had an issue. It caught me off guard for sure and frankly is a bit scary.

Post is for folks SA and to solicit thoughts on cause (prefer from someone who has had similar and found root cause).

Factory trigger spring?

 

[Tahoe1305]

That’s a good question. I believe it is. I frankly have a handful of tikkas and I know have only installed 1 aftermarket spring. Fairly confident it isn’t in this one.

Ever removed the trigger group?

 

[Tahoe1305]

I’m sure I have. It’s been in a KRG so had to remove the mag tensioner and attachment screw to get it in there.

I’ve shot this gun without issue for nearly a year in current configuration. That’s what’s bothering me most.

Guess one - trigger retention bolt loosened up.
Guess two - aftermarket trigger spring is fatigued.

I’d bet your trigger screw is loose.

Pull the action. If nothing obvious, without loading it, cock and put the safety on and see where the sear block is when the firing pin drops.

You can try the same pushing forward on the sear with your thumb and see the same.

Makes me wonder if the trigger has a broken pin or some other internal flaw.

I assume it is going off before fully on safe?

Good luck, and please update when you figure it out.

It’s behaving like the safety rear motion is the trigger. I’ll mess with it when I get back to CO later in the week. Not sure exactly when it’s firing but it’s during that rear pull of the safety.

Seeing trigger housing screw is loose

Thread 'Tikka slam fire PSA'

Apr 21, 2024

The other day I was out in the shop messing around and decided to pick up one of my Tikka's and practice manipulating the bolt rapidly. After a time or two something didn’t feel correct. It was releasing the firing pin on closing. Luckily it was on an empty chamber.

After a close inspection and tear down, I found the problem to be the Allen screw holding the trigger assembly to the action was loose. Upon further examination, it took roughly 1/4 of a turn from tight to allow enough slop in the trigger assembly for the seer to release the firing pin. I also noticed this screw does not have...

These are the two most seen causes.

Oh my. That doesn’t sound safe.

My 7 year old shot his first deer with same gun the previous morning. Was a great application of the rules of gun safety. Nice “sometimes” to see the “why” first hand.

You check the trigger screw yet? My guess is when you’re pushing the safety on, the bolt lock is going up and causing the trigger to drop because of a loose screw. When the trigger housing drops the pin is released.

you guys are talking about the bolt the bolts the trigger to the action right at the end of the trigger pounded screw?

Yes

Yes

Good mine is nice and tight. maybe you should Loctite it?

 

[rickyw]

Let us know what it ends up being.
Just picked up my first tikka last week.

I have thread locker on all of mine. But torque to 80+ inch pounds and you are probably good.
