625 JM Misfires Back From Smith

[Jeepster1]

Well, my 625JM arrived back from the Smith and Wesson today. Here is a direct quote from the sheet they enclosed in the box:

Repaired: Replace Firing Pin
Repaired: Replace strain screws

So, I guess they must have put in longer firing and did something with the strain screw. I did not know that there was more than one! It says "screws" (plural) not "screw" (singular). Maybe that was just a typo on their part? I'll take it out tomorrow and see how it shoots. Thanks again for all of your replies when I posted this two weeks ago.

keep us posted....the JM is a fine gun

Would be interesting to know what the length is of the firing pin they installed.

I don't think they would put a long firing pin in, it would become a safety issue if dropped. Lawyers need work too.

That was my opinion in his original thread, along with opining that they'd install a longer strain screw. It would be nice to know the length of the pin they sent the gun back with. Then we wouldn't be speculating.

Yes, Tomcatt- I agree. It would be nice if they gave me more information about the strain screw and firing pin length, or whatever else they did with the firing pin. Also, it would be good information for the rest of you to have. I just hope it works tomorrow when I take it out to the range. Would ya'll (yes, I am a Southern boy even though I live in Minnesota now) like a "range report?"

You could take the firing pin out and measure it.

S&W seems to put in short firing pins in their new guns to make it easier to pass drop tests in places like CA. I routinely replace them with the longer Cylinder and Slide Shop pin. Eliminates misfires, particularly when loading a 625 with unclipped ammo.

I've always assumed that "unclipped" ammo is why C&S pins are so long. They're waaay long, .515"? About right for unclipped ammo. On the 625's I've checked the rounds all headspace off the moonclip. Unclipped rounds have ~.015" more headspace.

My Model of 1988 5" 625-2 fires clipped or unclipped rounds with no problems. Of course, it has the firing pin on the hammer. It's also had a fine action job by Nelson Ford, and this has not affected its reliability in any way.

What does that have to do with the discussion here?

It Works! (625JM)

Just back from the range with the "repaired" brand new 625JM. 27 moon clips through it- 162 rounds- no cleaning anything off at all. Just paused a few times to let the barrel cool and change targets, etc. ZERO failures to fire. Win. 231 powder, 5 grains, Berry's 230 grain double strike bullets, Winchester primers. (This is my IDPA load) Loaded on my Dillon 550B. I wanted it to get dirty, so that it would be a good test. It got plenty dirty. I must say that Smith and Wesson got it right this time. But, I still have this nagging question: why don't they build all of them like this in the first place? So, I guess this is the last posting I'll do on this subject, unless something else weird happens.

Because the assemblers don't have time to tweak the gun. Slap it together, and promise a lifetime guarantee...
