Question about 9mm dies

[tpcollins]

I just bought a Ruger LC9S 9mm and will add those dies to my reloading arsenal. But I see dies listed as 9 x 19 and dies listed as 9 x 21. I bought Fiocchi ammo and those cases are 19mm long. and I auume any cases I buy will be the same.

Do I need 9x19 specific dies or will a 9x21 die set work equally as well? Thanks.

Don't over complicate thing for yourself. You want 9mm Parabellum or Luger dies. Those are 9 x 19.
Chances of you ever seeing a firearm that uses 9 x 21 are slim. It was invented to get around daft European laws that prohibit the civilian use of military cartridges. The two are not totally interchangeable. You can shoot the 19 out of a 21 but not the reverse.
