External Mods for ZP-5 Revolver?

Anyone know if there are any external mods for the ZP-5 revolver? I’m specifically looking a longer barrel.

How well does that shoot? What sort of range are you looking at with some accuracy?

I don’t own one yet, was just wondering wether I can get a longer barrel before I do purchase one.
Want it more for aesthetics as it’s really only for cosplay purposes.

Oh ok, I thought there was one with a longer barrel… That came out around the same time… Let me look…

Edit :
Yeah, this one…
