    So today I finally got another steyr owner to examine my M9 and he tells me that my trigger sucks. (which i've suspected all along) It feels heavier than 5lbs, which i've now been getting better at gauging since i've pulled various AR triggers this week around 200 times a day.

    It's a CDNN gun, purchased in sept 03. The frame says 11/01 and the trigger pin is in the center. attached is a photo of the spring I believe is responsible for trigger weight, along with the trigger and frame, although the serial might not be visable (24xxx)

    i'm wondering if this isn't the right spring or trigger, or if something's misaligned since it's been this way since day one, I just didn't know any better. If there is anyone who is familiar enough with the gun to be considered an armorer that could help, or if anyone here lives around Titusville, FL they could give me a hand, since i don't really wanna go through the hassle of sending it in to get it fixed if I can do it myself.

    thanks

    there are several tutorials in the tutorials & information section that detail your exact complaint.

    i'm not a gambling man but... i WOULD bet big that you have a nice colection of perpendicualr scratches on your firing pin guide rod.

    if you read all those trigger tutorials, you'll know exactly what does what and where to look to fix your problem.

    if you have any questions, fire away!!!!!

    i took the firing pin assembly apart and checked it. the striker's fine. the lock washer looks ok. it seems like the only way to get the spring off is to thread it off. i didn't want to fuss with that last night, but i'll take a look at it.

    I'll throw my 2 cents in and relate a problem and solution that somewhat mirrors yours.
    I bought a M9A1. When I got it the trigger was "pretty Good". I followed the tutorial on this forum that deals with the trigger spring and part #45 the weight or as you refer to it as the washer on the spring shaft that rides with the firing pin. I wanted to get the trigger to release the same every time I pulled it. The trigger would most of the time be nice, light, and break clean, other times it would be heavy and gritty. I polished the parts in the tuitorial. The spring(inside) and the inside of part #45, I polished by wraping a piece of 1500 grit sandpaper around a small finish nail. I then put the nail and an edge of the sandpaper in a electric drill, then ran the sandpaper inside the parts to polish. I inserted the guide rod into the drill chuck and polished with 600 then 1500 grit sandpaper.
    I LIGHTLY lubed the assembly and re-assembled. The trigger was GREAT,except that after awhile it got REAL gritty and stiff, then would go back to being GREAT for awhile.
    I thought about what might be happening and decided that the part # 45 was too big after the polish and was not riding the bar straight, but occasionaly twisting. I also called Steyr to find out what direction the bevel on part #45 faced. They told me the bevel faced TOWARD the spring. They also offered to replace the entire sub frame with trigger assembly on an exchange, VERY GENERIOUS of them. Instead I asked if they would send me a new part #45, they did, I got it in 3 days.
    In the meantime I took a large pair of channel lock pliers and squezzed the part #45 as tight to the bar as I could. THAT DID IT! the part #45glides along the bar tight with no slop, but still runs smooth.
    GREAT TRIGGER every pull!

    good tip!!!!!

    squeezing the weight.

    and now we KNOW that the bevel goes toward the spring.

    projekt. gently tug on the end of the spring until the end pops off. i kind of twist it. you'll have to be even more careful tugging the other end off because it's easy to squeeze the spring.

    well i just checked the trigger pull, albeit not terribly scientifically. I used a zip tie and a 5lb weight. trigger won't budge. i pulled a little more on the weight, and still nothing.

    I also tested it using a Gallon of water, which weighs 8 lbs and the trigger breaks right when the water lifts off the ground. so it seems that I somehow have an 8lb trigger. i suppose i'll be calling steyr on monday :(

    Your results are not unusual. All 3 of my "new style" Steyr M and S triggers measures between 6.5 and 7.5 pounds using a Lyman electronic trigger pull gauge. I've done the polishing but the pull still varies.

    I've found that flat to spring gave more consistent trigger pull. Had bevel to spring on M9 and after about 500 rounds, the inside and outside edges of the weight (washer) at the opening developed some burrs from impact I think. I had to knock them down with 1500 grit paper. Might have to ask Steyr Service about that. I'll have to try armored's trick of squeezing the washer down.

    Please let us know what Steyr says when you call. Thanks.

    FYI
    My M40A1 from the factory has the bevel on part #45 facing out.

    Still no trigger tutorials. Are any of you authors of the tutorials able to throw me a bone?

    i'm not sure what is up with making the trigger tutorials available.

    steyrclub has a very good working relationship with both steyr-mannlicher and SAI and it is quite possible that one or the other of these entities asked that these be removed from the site for the simple fact that it puts steyr-mannlicher in the position of paying SAI for warranty work on parts that were user modified. i am not privy to any such conversation, but that could certainly explain the tutorials absence.

    it could also be that either steyr-mannlicher or the armorer (s) at SAI read the tutorials and think there is nothing to be gained by performing any of the actions i described in the tutorials, therefore making them detrimental to the ownership experience.

    these tutorials were done before SAI was kickin' A and takin' names, mostly as a way of helping users diagnose and fix trigger reset issues. i'm not sure how effective these were at that intended purpose because on one hand, once these tutorials were made available NOBODY posted about a trigger reset issue. on the other hand, no one said they had fixed their pistol using these tutorials.

    let me try to find out exactly what is going on and try to get answers from the horses' mouth.

    BT,

    If either of your theories is correct, I'd suggest that whover is "they" make a post saying so. SAI have been champs at customer service for Steyr, and this forum is a major support for Steyr pistols. If such as you theorize is in fact the case, then I say "Step forward and speak the truth." It won't hurt anything and it likely help.

    My opinion,

    Either I'm Totally Blind or Just Really Stupid (latter)

    Did anyone find a trigger tutorial. I have searched and searched and searched. One post replied to look under the post "Crap Trigger". Still didn't see anything formal. When it comes to trigger work, I need something formal.

    Just like the previous post, I'm pulling all of the 7lbs. OUCH !

    1) Take pistol apart
    2) Fix problem or create one
    3) Put pistol back together
    4) Test pistol
    5) Cuss, cause you didn't fix it
    6) Repeat step one

    That kinda formal.

    Any help?

    Thanks,
    MTS

    Yup me too!!! Did the water jug thing, It took one full gallon and another with 3 inches of water in it. Went and put them on a scale and it came in just over 7 pounds :shock:

    Coming from the world of 3.5 to 4 pound triggers on 1911's this is hard to get use to!!!

    The one I am now worried about it what BT said in another post

    ''a quick check is to pop the slide off and push down on the sear/catch (triangle part). it should pop back up. if it's getting stuck in the down position, this can cause trouble. best to get this corrected by SAI/ steyr mannlicher.''

    Mine definitely does stay in the down position until I move the trigger..

    Not really sure what to do or if here is even where to post this. I took my steyr m9a1 to the range today (I bought it used) and put 100 rounds through it. I had no issues ohter than the trigger being super stiff. The trigger is much harder to pull on this compared to my ar15 and glock23 trigger (the ppk trigger doesnt count since its da on the first round and sa on the rest).

    The trigger was so stiff that after firing 60 rounds I loaded the mags back up and went to shoot some more except my finger was so sore and tired it couldnt pull the trigger. I havent ever had a gun with a trigger this hard to pull. What gives? I tried to access the tutorials like I did a few days ago but they are not working right now.

    I finally got trigger tune up to work.

    So I just tried doing this:
    "A quick check is to pop the slide off and push down on the sear/catch (triangle part). it should pop back up".

    Mine will stay down until I barely touch the trigger. Is this whats causing the problem or just part of it as a whole?

    ALSO I cant figure out how to get the slide plate off so that I can access the firing pin. This was easy on the glock I had but I cant figure it out on the steyr...
