model 1 1/2 2nd type

The hammer does not want to release to fire.
Can I fix this myself? (with a little help from my friends)

Is it possible to see the mechanism at full cock with the side plate removed? This problem is very unusual.

Here's a pic for you Mike
Thanks for your response

I think the trigger spring is incorrectly positioned or broken, the trigger should be more extended

Also note that the handspring and the hand are also poorly adjusted

It looks like the hook at the end of the handspring is broken so it can't manoeuvre the hand

Wrong main

The main spring in the photo is incorrect (not original) causing an incorrect arch and the hammer to impact the spring and freeze up.

Tap the main spring out and find an original.

Iby, the comments above are spot on. The mainspring is a replacement and not correct. The trigger should be proud of the spur. The trigger may be a replacement from a #2 Old Army as the trigger sear appears too long. The hand pivot pin may be broken as the hand appears to be canted to the side of the hammer. It should be parallel to the hammer.

To answer your question, YES you can fix it yourself, but you'll need a few parts. DO NOT touch anything with a file!

fix it

Well, I now have a variety of opinions.
My uneducated guess is the trigger spring option as the trigger does not feel very springy.
Does the trigger pin come out either direction?
Can it be removed without disassembling the other parts?
P.S. Thanks all

 

[mmaher94087]

All S&W pins can be driven in either direction. They are not tapered. Use 'cupped' punches (Brownell's) as the ends of the pins are domed and a flat punch will flatten the end of the pin and may slip off the pin and cause a gouge in the frame. Hint: work from the right side in case there is an Oops as the blem will be less noticeable.

I can't answer your trigger removal question as I've always pulled the hammer out of the way.

with spring and trigger in good condition , no problems with disassembly and reassembly.
For reassembly, I insert a small pin (lower diameter) on the opposite side to guide the pin and position the trigger and the spring

Hi There,


Here is a pic of the hammer and main spring for you to look at.


Cheers!

Edit: Added Pic of trigger.

Hi There,

The trigger may be a replacement from a #2 Old Army as the trigger sear appears too long.

I don't think so. The trigger in the pics has checkering on it and
my #2 Old Armies have smooth triggers.


Cheers!

OK, maybe not a #2 Old Army. There was a myriad of spur triggers that might have been fitted to this revolver. I still maintain that the trigger sear is too long. The photo shows the hammer at full cock, sear fully engaged in the hammer and the trigger is well back in the spur. The geometry is wrong. I have at least a dozen unidentified triggers both smooth and checkered that could be adapted to that revolver.

The spring is intact but not sure if it is original?
I should mention that the gun worked well when I got it. Maybe 20 yrs ago.
I had a Colt Lightning that went the same way.... Worked fine until it didn't

 

[mmaher94087]

Spring and trigger appear correct. If the main spring is removed, does the action cycle as it should without the spring?? I keep going back to the hand. The hand just does not appear to be aligned correctly.

 

[iby]

I will try the mainspring tomorrow.
Time for bed
Thanks to all

 

[mmaher94087]

iby, any news? I'm waiting for the other shoe to drop.

I got busy goofing on my NM3
I did loosen the tension screw and the mainspring just fell out??
The action still works without the spring.
I will take it further apart and take some pics.
Thanks for your interest

 

[mmaher94087]

I believe you have found the problem.

Any thoughts on how to acquire a correct spring?
