I've been having some issues with my TRG-22 trigger. When engaging the bolt slow, the trigger turns into a really heavy single stage. From my research, this means that the second stage is adjusted too low. Unfortunately, I had to adjust the trigger to the point where it is annoyingly heavy to get this to stop. I have shot another TRG-22 with a low trigger pull weight and no issues, this one needs to be far heavier to function reliably.

I'm thinking this means some portion of my trigger is worn/damaged. The corners of the cocking piece of the firing pin do appear to me much more rounded than the sharp/crisp corners on my AW bolt.

Suggestions? Input?

Thanks,

-Bob

I had the same issue and that remedied the problem. </div></div>I have played around with the adjustments as much as I can, since diagnosing the problem. The trigger is at the point where if I adjust the second stage 1/4 turn lighter, it will lock up when closing the bolt slow. It is way heavy compared to the other TRG I am familiar with, and not worthy of "TRG's have the best factory triggers" comments that I have read in the past.

I don't see anything at all wrong with the trigger group, however, the portion that it contacts on the bolt (is it the sear?) appears to be a bit rounded on the corners, especially when compared to my AW.

Edit- to clarify, I have been taking the trigger group OUT quite a bit in this adjustment process.

Re: Sako TRG-22 trigger

Hi bm11,

Perhaps you could post a photo of the potentially worn part?

There are a lot of TRG owners here that might be able to "look and compare" to provide you with a better evaluation of the part in question.

Re: Sako TRG-22 trigger

May have to dig up some older posts on this. It has been asked before. Sounds like one of the stages is not correctly adjusted. Need pic's of the worn piece so we can compare.

what velocity are you getting out of your shorty barrel bob? </div></div>The triggers are solid, overall, I think might might have been misadjusted, either by me, or the previous owner.

I don't know on the velocities yet! Last time we went to the range we couldn't get the chrono working, too bad too, as we were both shooting TRG's, his with a 26" barrel, mine with the 20".

The answer in that case was to adjust it a bit heavier. Unfortunately, I have to go way to heavy to remedy it in this case.

Do a search, this as came up several times and as I remember there was an individual in the know that posted a very detailed post with instruction on this.

Re: Sako TRG-22 trigger

I played a lot with my trigger and had similar issues when you went too light. If you lighten up the first stage too much, it will tighten up the second stage and lock up the trigger. Tighten up both the first and second stage, and make small adjustments one at a time to lighten it up. There is a sweet spot between the two stages. I would lighten up the second stage first, then work on the first stage.

Re: Sako TRG-22 trigger

Have you been removing the bolt when you re-install the trigger group? I seem to recall that being a requirement or you could cause major damage to the sear or related components.

Mine has to be adjusted quite a bit heavier than stock at this point to function 100%. Now- most of the time when it "locks up" it is because I am closing the bolt slow to look for it. But I want 100% function from this rifle.

ONCE when taking it apart, I forgot to take the bolt out, and that did lock things up pretty bad. I don't know if it did damage or not. I definitely did not reinstall with the bolt in, however.

Re: Sako TRG-22 trigger

And now, my trigger group seems to have failed all together. It has started to slam fire when I close the bolt, can't get a reset even though the trigger is hard, etc.

Looks like I am calling up Beretta USA tomorrow. Bad news is this- looks like a trigger group isn't priced much different than the bipod.

Re: Sako TRG-22 trigger

Well, I take it back. It's NOT going to Beretta USA, at least not yet.

With the resolution that I was going to have to pay, I decided "what's the worst that could happen," and tore apart my trigger group. I couldn't find any signs of excessive wear, so I reassembled it, and lubed it up with Rem Oil (not my favorite lube, but it seemed appropriate.)

Upon reassembly, it was a completely different trigger. Turns out they need lube for proper pull weight. I had no idea- I though most triggers run well dry. It certainly wasn't dirty, but the lube made all the difference in the world. Lesson learned!

Re: Sako TRG-22 trigger

I am glad to hear that it is working for you!
I have never had an issue with mine, but now that I think about it I have been feeding them a drop of CLP a couple of times per year.

Bob,

Mine has not been lubed since purchase. I think you may have fixed it by giving a thorough cleaning, but I don't believe that a thorough lubing would have freed it up without it being something else to begin with.

Josh </div></div>I can't agree with you there. It was at it's worst after I had douched it with lighter fluid (and let it dry.) It wasn't until I lubed it that it was magically fixed.

Your factory lube probably is still on the gun. I bought mine used, maybe it had already been cleaned (maybe most of the lube was gone when I bought it) which is why it was heavy to begin with, and why after cleaning it ceased functioning.

OR-

Something was sticking inside and the lube broke it free.

In any case, with a fair amount of dry firing tonight, no issues at all.

Re: Sako TRG-22 trigger

So here is my question - my trigger feels really good right now. It seems to act like a long single stage. I don't seem to have a solid two stage action going on.

I have tried adjusting the trigger and it what it does is goes CLICK when I pull it and then it needs a hard push to drop the hammer. Like 4kg.

When adjusted as it is now, the CLICK goes away and the trigger moves to the rear in what seems to be a smooth single motion.

What do others here experience?

</div></div>It sounds like the 2nd stage is adjusted as low as the first stage pull, eliminating the 2nd stage. I would increase the weight on the 2nd stage pull by turning the screw in front of the trigger unit clockwise, and perhaps consider decreasing the 1st stage weight by turning the screw at the back of the trigger unit (you have to take it out of the stock) counter clockwise.

Re: Sako TRG-22 trigger

I noticed that in cold my trigger wasn't happy. I think this was the result of lube getting in the trigger mechanism and getting thick as a result of it being about 18F outside. Some LSAT would probably have helped in these colder conditions.

Re: Sako TRG-22 trigger

I was having the non-existant first stage, heavy pull problem with my rifle as well. I just spent a few hours adjusting, and trying some different things. As others have mentioned, if your first and/or second stage is set too light, the trigger will go to a heavy, one stage pull. These are the measurements I took for my rifles, and they worked with both trigger groups. I backed off the first satge screw until it came out, and after many different adjustments, settled on 12 full turns back in. The second stage screw was bottomed out, and turned three full turns out. These adjustments should get most in the ballpark, and adjustments can be made according to taste, using half turn increments. These should give a fairly light first stage, with enough weight on the second, to tell when you are "there". I also found that the heavy pull problem will show up most often when the bolt is worked very gently. Another issue I was having was a sicky saftey. That is to say, it would work sometimes, and lock up on others. The saftey lever was bent, no doubt by me, frustrated with heavy trigger pulls, and it was rubbing on the bolt that retains the trigger group. Unfortunatly, I had to take apart the whole trigger group to get the piece properly straightened. I have both triggers adjusted exactly the same, and no longer have any issues. I hope this helps to solve some problems for fellas that were having trigger issues.

Re: Sako TRG-22 trigger

Arrrggggg, looks like I have some work to do.
I thought after a lighter douche and lube the problem would be solved but not so.

How long does it take to get back from the manufacturer if sent in for repair? Or should I just invest in a new trigger?
