Model 57 rebound slide spring..and pin?

Breakaway500 · Jan 4, 2019

I have a 57 apart and when I removed the slide spring,inside the coil was a SS pin. Since I've never seen this before in a S&W I thought I would ask. The trigger felt 100% normal,other than being gummy due to old oil. The revolver did not appear to ever have been disassembled after leaving the factory and has had minimal use..so is this pin something someone added (but why?) or could it have possibly been overlooked during assembly, and since it didn't affect the function was never found? OR..is the pin something that should be in the slide spring for a model 57? I looked on Numrich at their diagrams and saw no mention of this pin. There are no missing pins on the frame...but it does look like it could be one of them that somehow got into the coil at the factory? Anyone?

That is the slide spring pin and belongs in your revolver inside the spring. I had my model 28-2 worked on by a gunsmith and when he took it apart I saw the spring and pin removed.

Hmm..I've had a few 28s apart and none of mine had a pin in there..and I've had dozens of other K,L and N frames apart...and never had a pin in the slide spring.

But..anythings possible...could they all have had those pins eliminated? What is the pins function?

The pin is a trigger stop. Leave it out, put it back in, doesn't seem to matter much either way.

To clarify a bit I don't think the factory " tuned" the stop precisely enough to be really effective. If you wanted to spend the time you could use some drill rod and make your own and fit it more precisely.

Interesting...I wonder why no schematics show this pin..? If it is factory..why would it not be on schematics?

Judging by the guns that I have worked on it seems pretty hit or miss on wether or not the pin was installed. Also someone could have added it.

Ok..I suppose I'll just put it back in there. I'm leaving the springs stock...this is one gun I won't be keeping as I have NO 41 magnums or ammo.. and I am not journeying into that family of guns. iI is a beauty though..just wish it was a 27 or a 29...then t would not be leaving..

Seems to me that getting the spring back in would be even more a pain than it is without it.

I found a trigger stop pin in an old model 29 some years ago. I decided to remove it during reassembly with no ill effects. This is the only one that I have encountered in the many S&W guns that I have owned.

I ha e never seen that in any Smith revolver I’ve owned. Nor have I seen it in any schematic.

I have found a few of them it is what was posted above about a stop. Makes no real difference to me. You make them out of a old drill bit.

Puzzled me the first time I found one as I changed out most of my rebound springs.
