Hey leeblackman and people who know about triggers

Hey lee, I read you reply on the Ruger vs. Sig accuracy question.

I have a P89 9mm and just like you said, the trigger pull is awful. Last week , i got to try out my friend's P90 45cal. The SA trigger pull on it wasn't that bad! Not like a Sig or S&W revolver, but acceptable.

My question is, do you, or anyone out there know if you can tweak it? My P89 would be excellent apart from that.

I honestly don't know, I've never really seen a tweaked out Ruger, but I guess you could probably have a gunsmith polish all the contact points, that will give a smoother pull.

sounds like a plan.

Is that all there is to a trigger job? I thought that pieces were honed down and even ground to make pulls smoother.

It would be nice to get my hands on a Dremel Rotary Tool so I can polish up some pieces myself.

No thats not all there is to a trigger job, theres alot of things you can do, it just depends on the gun. I wouldn't use a dremel, use a polishing compound from the auto parts store. Alot of times doing trigger jobs involves changing angles and grinding or reshaping shears and hammers. I just depends on the gun.

If you don't have any gunsmithing experience I highly recommend taking it to a gunsmith and getting him to do it. He shouldn't charge you more than 35 bucks or so. Or at least get him to take it apart, show you what to polish, and then put it back together for you. Believe me, when money's low, I've done my share of that kinda stuff. Paying the gunsmith to do the hard stuff and letting you do the time consuming grueling stuff that would cost you the most cash.

Anyway, hope this helps.

The Ruger P89 will not smooth up to the point it is as slick as the Sig. Rugers are built for strength and service, not light triggers.
You need special jigs to hold the right angle for stoning triggers.
Attempting to do this work freehand without training is asking for trouble. A ruined gun or an unsafe trigger are likely results. Also, the hardened surface area on many triggers is measured in thicknesses of mere thousandths, easy to stone away and difficult to replace.

I didn't think to do the project myself, but I still would like to get a polisher for things like ramps and the like.

Thanks for the info so far all!

Improving a trigger pull usually involves reducing depth of engagement of the sear into the hammer notch, removing the undercut from the hammer notch and polishing (with a hard Arkansas stone) both surfaces as well as the sides of hammer, sear and trigger where they rub against the frame. The angle between sear and sear notch should be 90 degrees. If it isn't,and the error is in one direction, the hammer will be cammed back and the trigger pull will be hard. If the error is in the other direction, the hammer can force the sear out of engagement and you have an A.D. waiting to happen. Additionally, you may have to make a correction by adding metal to the safety to compensate for the shorter trigger and sear travel. If this isn't done, many altered guns will fire when the trigger is pulled with the safety on or will fire just as the safety is switched off.
This is a job to do by hand with patience, care, good lighting and a good magnifying glass.
