65 variation chart?

[fishwishin]

I have a 3” LS 65-5. I have looked online to see what “upgrades, improvements” the -5 has compared to the -1 through 4’s and beyond. I was not able to locate anything in a quick search. Does anybody have 65 variation data?

Thank you

Get yourself a copy of the Standard Catalog of Smith & Wesson, 4th edition. It has all the info you seek.
