Tikka T3X heavy trigger, easy fix

Hi.

Recently I've worked with two Tikka T3X's. None of them could be set lighter than 3-3,5 pounds. Still crisp and clean, but far from the 1,5-2 pounds we've come to take for granted in the older T3. I'm guessing this is a deliberate move from Tikka, in order to fit better into the US market. From what I hear, at least some states have a 3 pound minimum pull for factory rifles, or something like that. Correct me if I'm wrong.

The first of these two rifles was returned to the dealer for other reasons. On the second one I figured I'd give the trigger a go. Those familiar with Tikka/ Sako triggers will know that the adjustment screw stops against the trigger attachment screw, defining the minimum possible setting. So I just filed down the length of the adjustment screw slightly, allowing it to be unscrewed further. I filed off about 1 mm/ 40 thou, which brought it down to about 600 grams/ 1,3 pounds when the adjustment screw was resting against the attachment screw. So a bit on the light side for rough hunting. I screwed the screw about 0,2 mm back in, and got the desired 750 grams/ 1,5 pounds, measured in the curve where the finger rests. But now the adjustment screw was a bit wiggly, as it did not have a whole lot of grip left. I piled on loctite, and it seems to hold well. The trigger passed all sorts of banging tests, but l will inspect it next time my buddy brings that rifle along. If the screw is loose, I will fix it with a drop of epoxy.

Anyway, as this seems to be the new trigger pull of the Tikkas, this will probably become standard procedure. Next time I will start at 0,5 mm/ 20 thou, and take 0,1-0,2 mm at a time, until I achieve the desired pull, while the adjustment screw is firmly secured against the attachment screw. In this case 0,8 mm would have been good, but I suspect this might vary slightly.

From what I can tell, the trigger unit is the same as the old T3. Though I did not compare side by side. If this is the case, they probably just changed the length of that screw (and/ or spring) in the first place, making this an ok fix. But if someone has more in depth knowledge on the subject, please share.



Cheers

Magnus

A safety tip ...
Make sure that when the trigger is un-cocked that you can feel some resistance and spring back in the trigger.
If one skrew out the skrew to far i will loose touch of the spring and it can fail to cock or eaven set at supersensetive with only a hair of catch one the trigger edge .

The safe way is to buy a softer spring .

Re: Tikka T3X heavy trigger, easy fix
Thanks for shedding light on that. Important point. But yes, there was resistance/ spring back. Also, the trigger immediately responded to slight adjustments of the screw, which also indicates a certain spring tension. But certainly, if replacement springs were really easy to come by, I would prefer that. I didn't look too hard, but what came up was from us dealers. So didn't bother. It's just become such a pain in the ass to get some gun parts from over seas, so if I cant find anything readily available around here, I'll just modify what can be modified. So long as it's safe.

FWIW, my newly acquired T3x didn't have a "bad" trigger per se...but, I immediately spent the $10 on a new spring, dropped it in...and it's now both completely safe and wonderfully light.

I just purchased a Timney for my M70, ordered at 1.5 lbs (and supposedly tested as such). I also have the KRG Midas trigger. Honestly? I'd take my Tikka trigger with $10 spring over either of them...it's that good.
