Default .38SPL action arm replacement

Was just given an old .38SPL w.following characteristics:

4" swing-out hand ejector, 5-screw, w.strain screw
SN: C 78125

Was removing the considerable rust, discovered the action arm broken; am looking for guidance as to sourcing replacement and replacement procedure. I've taken apart my semi auto M&Ps, but never a wheelgun.

Thanks kindly for your replies and help. Happy to post photos if necessary, just let me know...

And, apologies if I've posted this in the wrong forum.

Thx!
Theman

I would suggest getting a copy of Jerry Kuhnhausenís S&W Revolver Shop Manual. There is a lot of good info in it including repairs like yours. You can source parts from Numrich, or eBay, or search for the part on Google. Good luck and post some pictures.

You can also ask the question in the gunsmithing forum section.

Welcome to the forum.

I am guessing that what your calling an action arm is the hand. The little thing off the trigger that goes through the frame to engage the ratchet teeth and turn the cylinder? But, thats guessing;

Better for you to go here and use this exploded diagram ID your part and when you are looking for parts or explaining a problem you can use the correct nomenclature and be correctly understood.

Smith & Wesson 10 Revolver Parts, Schematics | Numrich Gun Parts

The picture is a bit generic, but, it will get you there.

Go to Numrich Gun Parts, select shop by manufacture, then select S&W and then the model closest to what you need parts for.

They may well even have the part you need.

What makes you think it is broken??

Thanks gents. I spoke w.a local gunsmith over the phone and he identified, from description only (as I described it "the thin metal strip that runs from behind the trigger down through the grip to the butt"), but looking at the linked diagram, it's part 88 which is the mainspring.

I'm no gynecologist, but the fact that the mainspring is snapped in two pcs. and floating about aimlessly inside the grip is what leads me to believe it's broken [I know, you were thinking it was a more obscured part I couldn't see, of which would've been more difficult to ascertain the condition.]

Now that we know just which part it is I can see where knowing it was broke wouldn't be hard.

Easy part to come by and install. Once you have a mainspring if you need help installing we can help and point out several videos which will show what you need to know.

Mainspring replacement is an easy fix. Hope that`s all that`s broken.

What is this pin/where does it go?! I have scoured the schematic but can't determine. Had the side plate off in prep for replacing the mainspring, and despite my 'care' this appeared!

Edit: I can't post the pic bc I have no hosting resource. It's about an 'index-finger width' length, and from the wider end steps up to a wider shoulder, then steps down to thinner than the opposite end if that makes sense. The stepped up (widest part) shoulder is about 3/4 up the pin.

See if this works for pic hosting:

Sorry, I know that's probably hard to figure out, but i don't see anything else or any place else this may have a twin to reference.

Thanks!

Looks like it might be the bolt plunger, part #24 on Numrich model 10 parts diagram. Note there is a bolt plunger spring associated with it, #23.

Thanks - the cylinder doesn't stop so that must be it.

Holy **** that thing was a b!tch to find where it goes! The few youtubes I found for the model 10 disassembly didn't really call that plunger out/elaborate that it goes in/out the screw hole in the front of the trigger guard. Anyway, an hour of careful working and now I'm well-versed in dis/reassembly of the model 10!

Now then, my blueing technique needs some honing, but she's a damn sight better than she was!

Thanks for noting the spring; had you not, I'd have not been on hands and knees scouring the work area floor to find it!
