Steyr Trigger Job

[Wulfenite]

I've done a few searches but I cant find anything on this.

Is there any way to lighten or smooth the Steyr M serries triggers? Perhaps a link to a how to.

dremmel felt wheel and polish transfer bar.

that's about all you can do.

tutorial for removing action carrier subassembly at www.steyrclub.com under maintenance.

Oh and shoot it a lot, it will smooth itself out some.
As is i think it is THE best box stock DAO trigger there is.

I read the tutorial at steyrclub. I took the whole thing apart and cleaned it and reoiled. It really didnt help the trigger significantly.

You've got to be kidding about the "best box stock DAO trigger" comment. This trigger is too hard, the take up is too "wobbly" and the let off is no more crisp than a glock. If you were trying to sell me this gun I'd concede the ergonomics and grip are very fine, and the price is most reasonable, but I wouldent hesitate to pay another two bills for a glock, particulary since I know I can fix a glock trigger in 30 minutes.

I'm also perplexed by the striker/sear mechanism. The little pyramid shaped bump on the flat plade on the reciever,... is that the sear that holds the tail on the striker. Does it flip or back to cock? The functioning of the trigger isnt really easy to understand.

Ok mine is smoother crisper shorter than any glock i've ever shot, including brand new ones, idpa used ones, and cops sidearms.

is your trigger the old style? look to see if the pin that runs through it is at the midpoint or on the bottom third of the trigger.

[Wulfenite]

The pin runs through at the midpoint. Does that mean its new or old?

Wulfinite,

You're not alone with a less than perfect Steyr trigger. I have an M9, M357 and S9, and all triggers feel different. They are all new style triggers. Some varied from shot to shot more than others. My S9 seem to have the best trigger but it too sometimes has creep before let off and the pull weight creep up. Measured the M9 trigger with a Lyman digital trigger gauge and the pull varied from 7 to 8 pounds. No after market trigger parts to bring the pull to 3 pounds like the Glock.

The trigger action works by the trigger pushing tranfer bar(#16) back and pushing the catch(#10 piece with the "pyramid" bump in the receiver)back. The bump in the catch pushes the striker back a little (DAO) until the front of the catch slips off the lever(#11) and the strike then pushes the catch down via the engagement surface between the pyrimid and the tail of the striker and the striker shoots forward.

Polishing (I've done it) will smooth out the feel and may reduce the friction slightly but doesn't really reduce the trigger pull weight much (since the factory finish is already pretty good) or eliminate the intermittent creep. I think my intermittent creep problem is due to a slightly weak lever spring (#13) that sometimes allow the lever to not be in the full aft position when it is cocked and so the catch has to move the slight amount aft that the lever is pushed forward plus the normal disengagement distance between the catch and the lever. I would love to get my hands on a stronger lever spring to test that out but I can't even get a hold of a replacement lever spring at the moment with the Steyr transition.

I actually went out and shot the Steyr today and I have to admit its an impressive little gun. Great ergonomics and recoil characteristics. I'm still not convinced about the sights but I think with enough familarity I could learn to live with them. My biggest gripes are the trigger and the mag well. The mag well just seems to be designed to hang the mags instesd of drawing them in.

i polished everything. the the most dramatic change in smoothness came when i polished part 44. part 45 slides down this guide rod as you pull the trigger. if part 45 has a burr or has a sharp edge even, it can nick this guide rod and cause uneveness in trigger pull. polish 44 and the interior edges of 45 so it will slide more smoothly.

polishing the mating surface of the sear where it slides backwards/downward against the drop safety is also a good bet.

the biggest difference in pull weight came when i decreased the included angle of part 13 from 120degrees to approx. 90 degrees. the sear falls off of this post and when it does, pushes the post forward. the easier the post falls forward, the easier the sear falls off, the easier the trigger breaks. this may require more firing pin spring preload to pull the sear back onto the post during trigger reset however. mine didn't. preload could be added by tugging on the firing pin spring to make it longer. you don't have to go crazy. but don't do it at all til you have proven that your trigger has trouble resetting.

Wulfinite, I saw on the Steyr forum there is a gunsmith that works on Steyr triggers and can get them down to 2 pounds for Non-carry and 3 to 4 for duty guns. I forgot the gunsmith's name but I think the cost was less than $40bucks. Check out the Steyr forum and you'll find out the info.

My two cents:My S40 has the best trigger of all my CCW guns.That list includes a ParaCarry 45,a Glock 36,a Kahr K40(trigger's kind of weird,but nice),and both a Taurus PT745 and a 24/7-45.My USPf is my favorite,but it's too god-awful big for CCW.
