In Germany, Karabiner did not refer to "carbine length". It basically meant that the gun had tangent sights (not lange-vizier) and a turned-down bolt handle. Kar98b rifles,for example, are just Gew98's with new sights added and the bolt handle (usually) turned down.
The "kurz" was to designate that the K98k was shorter than the Kar98b, but both were considered to be "karabiners".
