You know what they say about a little knowledge being dangerous?

Now that I know how to disassemble the hammer group, what, if anything, can be done to "improve" the trigger system on a stock M57?

I searched about three pages deep and thought I'd just ask.

Link here or on the net?

Is it having trouble with hanging up or do you just want to smooth it up?

Just your typical, hobbyist "wanna tinker with it" syndrome.

(no more "hanging up" issues since I removed the safety)

Smooth it up would work. The weight of the pull isn't too bad, and actually kind of helps make it "safer" for car duty.

Sorry I can't help with smooting out, but I had the safety problem so I figured I could help if that was the problem.

I've just done mine. I swanny, my m57 had the hardest, heaviest trigger pull I've ever felt. One where you had to really concentrate on smooth increase in poundage on the trigger......to keep the groups under 80 inches at 25 feet....

It's a hammer notch job I think...cuz thats what I worked on..along with polishing everything near it...I used a very worn out dremel paper disk (I think it started out in life as 120 grit) taking 30% of the notch off. Brought the pull down to 7.5 to 8 pounds....

then I brought it to my gunsmith to go over and boy was he Urine. d

He stoned the notch and brought it down to around 4#s....very nice.

also flattened the trigger or unrounded it some...

I can break it down and show you the damage if yer interested with a photo.....

oh I also took a half coil of spring off of a spring I found in there....
