I have a Model 41 I got waaaay back in 1964 and it needs a new slide. The old slides (#10097) are no longer available but S&W tells me the new, current slide (#31055) can be fitted to an old gun if the old gun is sent to them.

Does anybody know what the difference is between these slides and what's involved with fitting a new slide to an old gun?

Thanks in advance for any information.

Regards
