If you have spare saurus models (if they are your base salamanders), you can eitheir convert some with pistols (from the Empire GW range for exemple, you have at least one pistol per sprue in the milia kit from memory), or if you prefer some lower tech alternative, or something that will require less exotic bitz, you might model them as saurus with javelins (or maybe other throwing wepons), as pistols rule wise are similar to throwing weapons with Piercing, and the salamanders are strong enough to justify the Piercing with throwing weapons.
