LIght firing pin strike

[Rolandedwinjohnson]

  My 625-8 is suffering from light firing pin strikes.  At first I thought that it was bad primers on some old 45AR ammo I had lying around so I threw that stuff out after soaking w/ WD40.
Today I took it out with some year old Russian, and RP, and Win 45ACP ammo. After comparing the firing pin strikes on all the ammo I tried to shoot I see a marked difference between those that fired and those that did not.

I shot both with and with out full moon clips, with mixed ammo, all the same type of ammo.  In other words I did all the possible test configurations.  No consistent difference in firing.

That leaves me with a firing pin problem.

Any one know how to work that issue on the 625?

Thanks

Try removing the grips and see if the tension screw on the flat spring has worked loose.  That screw will effect your firing pin strike.

You may need a higher tension spring. Pretty common since the end of hammer mounted pins. I had the same thing occur with an Uzi and the spring fixed the problem.

Thanks, that actually makes sense.  I'll give it a try

On my Mod 25-2 It has trouble with Winchester primmers. Federals work great, The screw in the grip frame is called a "strain screw" i beleive. I tightened mine also

I think Larry hit the nail on it's head.
shooter6br, these guns were often used for bullseye competion matches and altered to give ultralight trigger pull. Perhaps yours has been so altered? If by chance yours doesn't have the v-mainspring you could try a different mainspring and see if this puts it back to factory specs?
