View Full Version : New M27 trigger question

July 27, 2009, 07:01 PM
I have a new m27 s&w that I've put about 750 rounds through. The trigger is a little heavy but it's fairly smooth and I can live with that. The single action is pretty good. The problem is with the da trigger. After the action is staged, the last 1/8" or so is really rough ad gritty feeling. I've had the sideplate off twice to clean and re-oil, but it hasn't helped. What is it that I would need to do to smooth up that last 1/8" or so of the trigger? Thanks.

In general with a revolver it's best not to "stage" the trigger but to pull it clean through. Staging is a bad habit and in a self defense situation not desirable. Yes it is harder to shoot but it can be done with enough practice. Remember when you pull the trigger on a wheel gun you are moving alot of mechanical things around so it may not be real slick especially on a new gun. My new m686 is not as smooth as my 1983 m686. Now this is all said assuming their is no mallfunction your gun, if you feel there is something not right then send it back to S&W. Now unload your gun, open the cylinder and hold back the cylinder latch and pull the trigger da. Is the roughness gone? If so then your hand may be too long or there is some problem with the cylinder ratchet. If not then it is internal. If you feel up to it get the Kuhnhausen manual or search the internet and try to smooth the action yourself. If it for range use only than by all means try some reduced power springs. If you feel it is in the hand/ratchet interface then send it back to S&W. Hope this helps.

Thanks. Ya, I did open the cylinder and pull the trigger and it is smooth. We took another look and the cylinder is locking up just slightly soon and my buddy determined that the hand is just a touch long and that is causing the roughness. I ordered another hand from brownells and we are going to see if we can fit the new one better than this one, that way I don't screw up the original. We did open it up and smooth any rough spots but didn't hit any critical parts. It is much better.

I am trying to break myself of the habit of staging but like you said, it's easier to shoot better groups by staging but hey, this gives me more reason to shoot more often and practice.

Thanks again.

It sounds like the roughness comes in when the hand goes up past the ratcher tooth. I don't think I would mess with the hand as that condition usually works itself out and playing with the hand could end up with the cylinder not locking up. My suggestion is to load up with snap caps and spend a TV evening dry firing.

(With some of the stuff on TV, it is tempting to load up with live ammo and take your frustrations out on the screen; I strongly urge you to resist, since new TVs are expensive.)

I talked to S&W and they said basically the same thing. They said after about 500 to 700 rounds, it should smooth itself out. Problem is, I've shot about 1500 rounds with a lot of dry firing and it's still the same. I figured that's why I ordered another hand so if I screw it up, I'll put the original back in.

And let me tell you, there are plenty of things on that TV that I'd like to load up and shot at but, as you said, I'd rather spend my money on ammo than a new TV, so....:cool:
