19-5 Firing Pin Loose Rubbing Frame?

[HEADKNOCKER]

The 19-5 I just aquireds Firing Pin has no spring tention like other hammer mounted firing pins I've seen, It rubs the frame at the top of the hammer window & there's a notch were it hits, If I hold it up it catches on the frame a bit, hold it down & it clears the frame..
I've never had this type of hammer mounted firing pin out but it looks to have a hollow pin that retains the Firing Pin & whatever spring it has that mine is either missing or is broken..
What would you do?
Order parts from S&W?
Call for a repair & see if they'll send out a pick up tag?
I'll be calling them tomarrow..
Thanks, Here's a couple pics One with the pin moved up the other with it down, It has no spring tention as if the spring is non existant?

Headknocker, not to worry. That's the way it is supposed to be. K frame guns didn't have a spring loaded pin like N frames.

I've had other say something similar but this pin does hit the frame & there's a groove either cut for it or the pin has made this over time..
My Only other K Frame is a M547 & it's dual FP setup is in the frame..
I'll try an get a pic of the frame when I get home tonight..

What would you do?

Enjoy your gun and don't worry about it. Some of my Smiths have springs some don't. Many are just like yours and if you hold the firing pin up, it will touch the frame. They work fine.

I've just never had one that was loose..
I called S&W & left a voice message with no responce after two days now..
The top tip of the firing pin is being ground away, see pics above, It's not rounded as much as it was originaly, I assume the with the inertia of being released the pin floats up & catches the frame, There's a groove worn in the top of the hammer window that matches this & it still slightly catches.. I cold blued this area with a touch up blueing pen set but still wouldn't think this is correct.. Look at the pic below of the damage that this has done to the frame & tell me this is normal?? Possible?
You would think this would rob the hammer of some of it's strike capability or possibly cause light primer strikes..
I'll be calling S&W In The Morning.. AGAIN!!
Thanks to all who have replied..

Called S&W again today & got right through..
The tech told me that the K Frames with the hammer mounted Firing pins are called floating pins, They Can & will rub the frame exactly like it's doing..
He also said unless it has trouble to not even worry about it, It's been like that for 20 years & all is good..
I suppose I'm satisfied with his answer..

I was wondering, why does the firing pin have to move like that? I have a model 19-2 k frame that has the same feature.

The floating hammer-mounted pin feature is designed for the manufacturing tolerances built into machining the frame, hammer, etc. If the pin was perfectly rigid and unmoving, constant impact against the frame with just a few thousandths of misalignment will reduce reliability, and eventually, cause the pin to fail. If manufacturing tolerances were extremely close to design and unfailingly accurate, the floating pin design would not be necessary. Since manufacturing techniques are what they are, as tooling wears, and fixtures and positioning changes, other dimensions are designed to accomodate these changes. The floating fp is one of them.

Excellent, thank you.

 

[HEADKNOCKER]

Yes Thank You!!
This is one of those things were looking too hard for something wrong had me looking harder
I still can't believe that the FP rubs/scrapes the frame but the pics prove that it does..
S&W says it's fine??

I have shot and supervised the shooting of a couple of gazillion rounds through S&W model 10 and 64s with just that sort of "firing pin" (hammer nose) at the academy and local ranges. They work fine that way. That's how they are supposed to work.
