Sorry, I know this is a Smith forum, but perhaps someone can help me here. I have an Astra 357 4" revolver that looks very similar to the pic I posted. It seems to closely resemble a Smith 5 screw, I believe. Anyways, I took ownership recently, aware that the double action feature didn't work right. I took it apart, and it appears, according to an online schematic, that I am missing the sear pin and sear spring.

I guess my question is, based on posted pic, can someone please list me S&W models that I could research and perhaps find a sear spring for? I know interchangeability might not work, but Astra revolvers are uncommon and parts are near impossible to find, and I'm willing to give it a shot. Might work.

I found an online store that has the pin, but not the spring.

Thanks!

Here is a schematic and on-line source of parts:
Numrich Gun Parts Corp. - The World's Largest Supplier of Firearms Parts and Accessories

I note that they are sold out of sear springs. Perhaps you could talk to a gunsmith or a machinist to see if you can have one made?

Or go to the Gunsmithing Forum of this website and ask if anyone there would be willing to do this... (?)

From the picture that looks like a small coil spring. I'd either buy a small coil spring assortment pack like Brownells sells or try a S&W cylinder stop spring. You'll probably have to trim the spiring down and will probably make the first one too short, but should be an easy fix. Heck, a ball point pen spring might work.

Sorry for the late response... I forgot to look, LOL

Thanks for the ideas, especially the ballpoint pen spring

The ball point spring isn't a laughable idea; I regularly improve the trigger pull of Lugers by substituting a hunk of ball point spring for the regular spring which I guess they make needlessly strong for combat conditions.
