See ~08:15 minute mark.
I don’t know what happened.
I’d double-check to ensure the top of the mainspring isn’t somehow broken.
I’d double-check to determine where the top of the mainspring hooks onto the “stirrup” is ok.
Hopefully all relevant parts are unbroken and it was some weird mis-assembly issue.
Here’s another video: https://www.youtube.com/watch?v=YPoOqBArPaM&t=271s
Look, starting around 16:25 minutes for perhaps some better video. The talking gets a bit distracting. Turn down the volume which may help.
Chalk it to “anomaly”. Odd shit happens occasionally.
I do know my way around DA Smith Revolvers; but if nothing is broken, everything tight- that shoulda never happened.
You might check to be certain Strain Screw hasn’t been shortened for a lighter, DA trigger pull.
If it has, there isn’t the tension on Main/Leaf Spring, which conceivably cause Mainspring to pop out.
When I removed the mainspring as part of replacing the safety with the Original Prescision button, I made sure to tighten the strain screw very tight, and with Blue Loc-tite.
I’ve had no light hits, and the first thing I checked was the strain screw by attempting to tighten it. Didn’t budge. Then I loosened it and it took considerable effort to defeat the Loctite. With screw nearly out I was able to put the mainspring back in place without removing the side plate.
I removed the mainspring & sidepate last night to inspect everything.
Probably gonna sell it. I lose faith in a gun easily.
I’ve been dry firing it a bit. Everything feels fine.
Perhaps something shifted when the cylinder was tight because of the lead & grease debris?
I’d have to remove my optic and mount as well as the safety hole plug and stock grip to put it back to stock if S&W would send me a return label.
They’d probably fire it, do a cursory inspection, and send it right back.
At least if my Colt King Cobra breaks I can send it back as-is because it needed nothing changed. Awesome revolver. Well, except for several reports of broken hammers.
I’d love to see someone make some milled / forged steel hammers to put in new Colts. I’d do it. Not sure if broken hammers are an Anaconda or Python issue. Could just be Cobras / King Cobras.
If I shrink it, you won’t be able to see the detail.
Looking at pictures on the internet it seems S&W has changed the way the mainspring attaches to the hammer.
I found images of hammers that have a pin retaining a piece that has the pegs the mainspring loops on.
Mine doesn’t have that pin. Instead the hammer has a horseshoe shape the piece with pegs, which is also a different design, fits into. There is no pin retaining it.
The hammer isnt broken, it was made this way. I took pics with my phone so I could see fine detail.
Good Lord.
Cost cutting measure allowing elimination of the two parts that used to hold top of mainspring in place.
Hard pass on the MIM “better” crap.
I think this is the source of your disappointment.
If you don’t remove the sideplate and Mainspring disengages from the Stirrup, you couldn’t visually confirm that the two parts were correctly connected before tensioning the spring again. You were just fishing in there, blind and didn’t get the hooks completely onto the stirrup pivot.
I have no interest in a 7-shot but, since its busted, I’ll give you a dollar for it. :laugh:
The spring never should have popped loose the first time.
I, too, was surprised I got the mainspring set again after removing the strain screw but without removing the side plate. Got lucky I guess. It seemed fine.
Later I decided to do a thorough inspection and removed the side plate, strain screw, and mainspring. Put it back together and again, it seems just fine.
But I don’t trust it enough to carry it now and never will.
