Shortly after I received my Hatsan model 125 back in January the trigger blade broke right where the adjustment screw hole goes through the trigger blade. After some back and forth with Hatsan's customer service people they sent me a replacement trigger blade. I installed the blade, adjusted it, and I've had no further complaints about the Quattro trigger. The rifle broke in to be a fine shooter and all has been well since. Until today... I went out to re-zero the scope after I dropped another rifle on it. I got off two shots and then the trigger blade snapped under my finger as I was squeezing off the third one. Same place as the first one.
Has anyone had this experience? It seems to me that the adjustment screw holes are a design flaw.
I have sent an e-mail to Hatsan customer service and hopefully they will agree to provide me with another trigger blade

The Quattrro trigger blades I have are pretty soft. Some form of pot-metal or die cast zinc?
While it could be made stronger, I have never seen one break as you have described. Can you post an image of your trigger blade so we can see where the break is located?

Yes please. I have never seen one break either. Do you hange your gun up by it's trigger? ;D
The stock screws are super soft also. Even with a hollow ground screw driver, i recommend every Hatasn owner to get a spare set of stock screws.

I e-mailed these pics to Hatsan customer service. Looks like they are going to send me another replacement trigger blade. ;D
The lower blade in the picture is the replacement that failed yesterday. The upper blade is the original that broke a couple of weeks after I received the gun. They both failed along the axis of the adjustment screw hole but each one broke at a different hole. The original failed at the front adjustment screw and the replacement failed at the rear adjustment screw.
-
Maybe next time you should chase the threads before installation?
I assume that the hole was drilled too small and the pressure of an oversized screw just split it.
Bummer! ??? :'(
Good luck,

Does your trigger pull feel exceptionally heavy?

Those breaks are along the weakest parts of the casting.
The stock screw holes should have been drilled and tapped from the factory for a proper "no stress" fit. There is a cross drilled hole in which a short section of plastic rod (poly?) is pressed. That plastic is inserted after drilling and tapping, and provides friction for both adjustment screws so that they don't move (self adjust) during rifle vibrations.
I don't remember the metric size, but I've replaced these screws on a few Quattro triggers. The ones in my photo are Philips head screws (slightly longer and different drive head from stock screws) which are ground to custom lengths I determined through testing that particular trigger. If non-stock non-metric screws are substituted, they could be over-stressing the factory tapped holes.
I'll assume you are using the factory adjustment screws and are NOT doing something unusual like storing the rifle by hanging it from the trigger blade. In that case you are really unlucky to get (2) trigger blades to fail in that rifle.
Glad Hatsan is sending you a new blade. If (#3) blade breaks the same way I'd re-think bad luck and suspect you are doing something unusual that is causing the problem.

It's weird. The gun spends most of its time horizontal on a gun rack. The adjustment screws are stock. I never touched them except to do the initial adjustment on the trigger. I haven't shot it in three months because of shoulder surgery. I haven't done anything unusual with the gun. I hit the scope accidentally with another rifle and was attempting to re-zero when suddenly the trigger seemed to freeze. When I relaxed my finger pressure the broken trigger blade fell out of the trigger guard. I have the trigger weight set at around 5-6 lbs. because that's what I'm used to and because I'm afraid to set it too much lower.
And yes, I'm starting to wonder if it something I did. But I can't think of what. I don't abuse my guns intentionally. :-\

Well if you get some JB Weld, you can have a bunch of spare trigger blades... ;D ;)
-Y
PS maybe try and set the next trigger weight to around 3 lbs?

Believe me, I've spent a lot of time pondering how to weld the pieces back together! :P
I'm not sure 3lbs. is achievable with this trigger or if it would be safe.

"trigger weight set at around 5-6 lbs"
Hummm.......is the pull weight from the factory set lighter?
Straight from the box I reset my factory HW "lawyer settings" to "trip the sear" at 2ish lbs.
Anywhoo....definitely a "different strokes for different folks" issue for sure! :)

While I'm familiar with the Quattro break-barrel trigger, I've only used or tuned less than 30 of them. All on refurbished rifles and bargain sales of old (but not preowned) "stale" warehouse stock rifles. To date none of my Quattro trigger blades has broken. However, it would not surprise me if there was a more recent batch of Quattro trigger blades that had a casting or machining defect. If that is the case, hopefully you will get a good one this time.
A trigger weight around 6 lbs should be well within the range this trigger blade can handle. I prefer to set my Quattro triggers around 2.0-2.5 lbs. That is my ideal trigger weight range for best accuracy when shooting paper, cans, or pests. I know they can be adjusted lower but I simply prefer not too.

My guns (PB's and air guns) are all cheap walmart junk or milsurps. I'm used to long, heavy, gritty, creepy triggers. I don't expect my cheap guns to have great triggers. I am non-technical. The few times I have messed with my adjustable triggers I have only messed them up. And the Quattro has TWO adjustment screws! I'm a "If it ain't broke don't fix it" kind of guy. Triggers scare me with all those fiddly little parts and springs so I don't mess with them.
Mike, thanks for chiming in here. Your advice is always appreciated.

You did nothing wrong.
That is, or was, a bad trigger blade!
Let me know if you need one. I'm sure I have a few left around here some where.

Thanks Jeff. The replacement trigger came from Hatsan this week. I sent an e-mail explaining that a second trigger blade had broken and they shipped me a replacement PDQ. Kinda makes me wonder if Hatsan knows something?
Anyway, the latest replacement is a new trigger blade. The first replacement was obviously removed from a refurb. The newest blade came with no adjustment screws or the Delrin bushing. I haven't installed it yet because I just don't have room on my workbench right now.

The trigger on my H130 broke just like that. I have a Dominator that I keep for parts. So, I robbed the trigger from it. But I'll be contacting Hatsan to get a replacement. Its certainly a weakness in the design. I made no modifications to mine. It just broke on its own.

I love it when old threads are resurrected.

I keep a spare trigger now just in case. I haven't had one break in a while so maybe it was just a bad production run from Hatsan?

LOL. But, the alternative is a whole new thread on the same topic. Six of one, half dozen of another. I’ve not had one break knock on wood so it’s a new thread to me ha ha ha.

I'm looking for a spare to buy from somewhere. My internet search for a replacement trigger dug up this old thread.
My trigger broke exactly like the one in the OP's pic above. so why start a new thread?

Reading back over this post it struck me how much my attitude has changed since the OP. I still don't like to fuss with triggers but I've become a lot more confident when I do. I eventually replaced the adjustment screws in the Quattro trigger with longer screws and learned to adjust the trigger to about 3 to 3.5 lbs. I eventually mastered the mod 125 and even bought a .25 caliber version. Both have very nice triggers now and both are surprisingly accurate for magnum springers.

The fact that old discussions are all here to click and read, and possibly reply to, is the BEST feature of online forums, as opposed to social media, where interesting stuff flows downstream in a day or three, never to be seen again.
Spring guns sometimes take years to reveal all there is to know, good and bad. So it's all well and good that discussions sometimes run for years.
Over time I have seen many Quattro-triggered Hatsans, for sale and otherwise, with the comment: "The trigger snapped and has been replaced". These are not isolated incidences, really.
My H135 trigger is still in one piece, but I did buy a cast bronze replacement trigger, by a Russian guy, waiting for the day when the snap happens.
-
Yeah, I'm wishing I had gone ahead and gotten two trigger blades from Hatsan just so I can have an emergency spare on hand.
The cost wasn't bad. $9 for the blade and $9 additional for shipping. Shoulda gotten two...

Care to share the link to that bronze trigger?

It was years ago, on Ebay. I don't have a link or any contact info.
