I reload for 9mm and so it makes sense to get .357sig that way I use the same bullets to load both calibres. The down side is factory ammo/ brass availability and cost.
If I get a .40 I can use the dies and the bullets to load for 10mm when/ if I get one (always wanted one). But .40 bullets are more expensive than 9mm/.357sig. On the plus side .40 factory cost’s less than .357sig
