    Howdy Boys :)

    I'm very curious about trigger pull variances for the M and S Series Steyrs. For those with a trigger pull guage or some other way of accurately measuring their trigger pull, please post your results here. And, please be as accurate as you can. I'm not interested in hearing, "...oh 4-8 bs....". I'm talkin', "4.2 lbs" or "3.8 lbs", that kind of accuracy. I'll post mine tomorrow, when I get a guage that works. :oops: And, if someone will offer a simple and exact method for determining trigger pull, short of actually having a trigger pull guage, plz step up to the plate and post that info, ASAP. Thanx.

    If you have a fish weighing scale, you can use that. I used one once on an M-16 in a pinch as we had to get the weapon out.

    OK

    I went and picked up an RCBS trigger guage today and after BT's trigger tuneup its sittin' pretty at 6.25 lbs. I wouldn't mind if it'd go to 3-4 lbs, and that's what BT's workin' on. Wish 'im luck on this project. We'll all benefit from it.

    All these have had the polishing and spring tweaks done and do feel much better than when fresh out of the box. And hope to have continued improvements from tweaks offered by BT and you all on this site.
    Measurements using Lyman electronic trigger gauge, average of 10 measurements.

    S9 avg 7 lbs 8 oz, high 8 lbs 5 oz, low 6 lbs 5 oz.
    M9 avg 6 lbs 1.5 oz, high 7 lbs 2 oz, low 5 lbs 7 oz.
    M357 avg 6 lbs 7.5 oz, high 7 lbs 3 oz, low 5 lbs 13 oz

    Please post results when you get it back fom SAI and find out what they did if the trigger pull is reduced. When I asked about the heavy OTC trigger pull at the old service center, Dennis said that they would try replacing fcg parts to try to reduce the pull. Didn't seem to be worth the FedEx shipping and wait at the time. Thanks.

    I checked the 5-6 lb category. But don't put too much stock in the accuracy since I measured it with a fish scale pulling on a string looped over the trigger! It varied a bit depending how high or low up the trigger the string was for a particular pull, but it looked like the avg pull was about 5 1/4 lbs, whatever that's worth. Surprisingly, it measured about 1 pound lighter than my Bulgy Makarov's single action pull. 8)

    Hi Guys :)

    Thanx for getting involved. I hafta tell ya, after I went and purchased a new RCBS Trigger Pull Guage, I had to practice a bit to get consistancy. Obviously, I wasn't the only one. <shrug> I tried a digital fish scale when I told a friend I was goin' to town for a new trigger pull guage. He suggested we try his fish scale and so we did. It scared the Hell outta me seeing anywhere from 8 to 12 lbs! My trip to town became more hectic. My first try with the new RCBS was in the truck in front of the dealer. I musta looked like a junkie. :roll: It read between 5 and 8 lbs. When I got home, I found that if I put my M357-A1 in a vise, racked the slide with the mag removed and disengaged the trigger safety before putting the guage to the trigger, a smoothe even pull lead to a very consistant 6.25 lbs. When I didn't go through this routine, I was getting readings from 5+ lbs to sometimes over 8 lbs. The scale reads to 8 lbs. Pull was more erratic not using the vice. Anyway, thanx again for your participation. Hava great week.

    They said they replaced the whole trigger bar, and also the firing pin spring, b/c it felt a little tight. When I get it back, Im sure I will go back through the tune up, but Jeff said it was sitting at about 6.5.

    Thanks RC. I wonder how much do the FP springs vary and if SAI haveFP springs of different weights.

    I measure the trigger pull with the back end of the slide and grip sitting on the edge of the bench (muzzle pointing up) and pulling down on the trigger with the gauge. To make it easier and safer, magazine out, no ammo in sight. Rack the slide all the way back each time to cock. My Steyr triggers do have quite a bit of vairation in the pull weight and creep and I can feel it during dry fire. The nice clean breaks usually feel lighter than the ones that are creepy. Have already done the trigger tune in the BT tutorials and continue to tweak with lube and more polishing here and there to try and get more consistent and lighter trigger. would love to have differnt springs and fcg parts to experiment with but will have to wait until the Steyr gets more aftermarket support or Steyr offers those parts.

    I did my test with the vise also. The rusty fish scale did show a consistant pull just over 6#
    I did the firing pin and part # 45 "donut" polish(this was done before the trigger pull check). On the "good" pulls the trigger was VERY nice and light, but I still had the hard,scratchy pulls.
    I called Steyr and was told that the #45 bushing needs to have the bevel face the spring. I examined the assembly and though that if tha #45 bushing was to fit in that recess on the rod it should be snug so it would not cock while running the rod. While seated in the channel on the rod I squeezed it hard with a large channel lock pliers.

    When I re-assembled the pistol and tried it the trigger pull was always SMOOTH and light. It remains so.

    Armored: when you tightened #45 with channel locks, did you face the bevel toward or away from the spring?

    Good deal, Cakes :)

    That's what I got from BT's tutorial work. I never sent it to the shop for a trigger reduction service. Never needed to. <shrug> Guess BT knows his sH*t! 8) Hava great Labor Day weekend.

    both of mine are breaking pretty consistently at 5.75 lbs. i noticed that if i put the arm way up by the top of the trigger, closer to the slide, that it goes way up into the 7 pound range. and if i just barely grab the tip of the trigger, it breaks under 5 pounds.

    where i actually squeeze the trigger during use is the 5.75 lbs.

    I just noticed that I can change "felt" pull also. I grab in the lower part, but I've been using the pad of my finger. I was tought that it is the right way to shoot it (by a 2 1/2lb custom 1911 shooter), but when I grab it at the bend in my finger, it feels half as heavy. Im going to try this next range trip. Might make it feel that much better.
