[Star Wars] If Mandalorian equipment evolved with "killing Jedi" in mind, why didn't slugthrowers become part of their gear?
gpt
In legends slugthrowers were a vital part of mandalorian armories. In canon the mandos have had nearly 1000 years of regression as they lose major production of wartime materials to the pacifist majority on mandalore. This leads to a scarcity of mandalorian slugthrowers so high energy blasters were the next best option. We do see a larger than average reliance on explosives and beskar based weapons like the whistling birds.

So TLDR slugthrowers require munitions and supply chains that modern warrior mandos lacked. Slugthrowers became a specialist weapon rather than standard issue.
