Something I figured out recently that I should have figured out long before.
The way Smith and Wesson's numbering system generally works. Generaaly.
I have a 686-3. Does that mean their were almost 700 models of revolver before that? Not really.
That first 6 means it is made out of steel (stainless genrally.) A 2 digit number is the classic model number and made of regular old steel. Like blued Model 10's or 36's.
A three digit model number that begins with a 3 is made out of scandium alloy. A 4 at the beginning is aluminum.
So when I am looking for a 617, I want the clasic .22 firing model 17 but made with stainless steel.
So what is a 642? It's a small matte silver snubbie, but isn't stainless steel. There is a model 42 that is matte black in color, also made of aluminum. So I don't have the numbering system figured out entirely.
Oh and the '-3' after 686 on mine? I think that is an improvement over and earlier generation. There was a recall on -1s and no dash 686's. Or that is the theory.
Neat site though, FirearmsID.com. Check it out.
