625-8 Problems

[stefanveres]

Hi,

I am new owner of an S&W 625-8 .45ACP with 5" berrel.
I took it to the range yesterday, shoot with it 200 round nad noticed, that I had more and more light strikes. The revolver is not tuned, so I took the dam thing apart and when I took the grip off I noticed, that the mainspring slides do a side.
I repear it and took it to the range today for shooting 200 rounds again, then at home I dryfire it a feew time, took the grip off and noticed, that the mainspring slides 2mm to a side again.
I bought this revolver to shoot IPSC whit it, so I do not want to tinkel with spring ewery day.

What could be a problem?

I must say that I am from EU.

Regards,
Stefan

Stefan,
Make sure that the mainspring strain screw on the botton front of the frame is fully tightened - that should solve your problem.

I'm going to say the obvious, and I've had to do this on my 625-4. Put blue Loctite on the strain screw, and snug it down tight. It sounds like your strain screw is backing out with recoil. Tighten it down and use a thread locker and you should be all set. I'm not saying this is your absolute answer, but it fixed a similar problem I had.

The screw is tight ( it did not moove since yesterday ).

Why should the mainspring moove anyway?

Did you buy the gun NEW from a dealer or used. Many want to be Smith and Wesson gunsmiths think that the way to do a trigger job on a Smith is to back out the Mainspring strain screw or worse yet they will file down the end. NEITHER works BOTH will lead to light strikes. If you can move the mainspring side to side with the strain screw turned in all the way the screw is too short and should be replaced. If you bought it new S&W "should" correct it. If you bought it used you may have to pay for the screw yourself. Make sure you get the correct screw for the butt configuration.

I bought it new.
There is a problem with return. The S&W dealer for Europe is not in my country, so I have to put together a mountain high of papers only to send the gun back and then wait feew month ...

There must be a way to repair it at home.
Please adwise .

You can take a spent primer from a fired round and remove the anvil and back out the strain screw and place the spent primer on the end of the stain screw and tighten back tight.
This is a temporary fix and it will tell you if that is your problem. If that cures your light strikes then you can order a new strain screw and replace it yourself. I have used this method and I still have one gun that has been used this way for a couple of years. Hope this helps.

Now that's a cool idea. It could help in the off chance that the screw is too short, or the spring is too weak. Either way it won't hurt to try.

When I put the main spring back in place and tighten the screw back, I dont have light strikes no more, so the screw is OK. I have problem, that the mainspring is sliding to a side.

Would it be possible to post a few pictures that show the problem?

Your mainspring may have a sharp point on the end which provides little surface area and recoil causes it to shift to the side. I would file the point just a "very little" to make it flat and reinstall tight. Same idea as the primer cup but a permanent fix.

Thanks.

I wil shoot a feew more rounds and than I will look again, if the problem is solwed.

You said it wasn't tuned... are you sure no one ground/filed the strain screw a bit, a common method of lessening the pre-load and DA trigger pull? If it bears down on the strain screw at all, it'll secure the spring. Of course, the more pre-load on that hammer spring, the harder the primer hit and the greater the DA trigger effort required. A letter to S&W would likely get you a new strain screw gratis. Faster than that here in the states, a trip to a home center/large hardware store, can get you an Allen headed .5 inch SS set screw - it's either a #6 x 48 or a #8 x 48 - sadly, I have forgotten! And - if you need to secure the threads, use blue Loctite - it can be broken free with a little heat (The strain screw must be loosened to change the hammer leaf spring - or to take the lockwork apart.). Good luck!

It is brand new from the box.

Even if it shifts to the side, the grips will keep it in place, amd it's not going to go anywhere. As long as the screw is tightened and you get goodmignition I wouldn't worry a lot about it. Just shoot the thing until your new screw comes in.
