Time to take it to the next level. You aren't fully "that guy" until you are making your own grenades and plastic explosives. You need to learn the rules for crafting explosives, guy.

....in 3E, my character Leela had all the necessary skills as well as the workshop to make her own explosives. One of her long term projects was crafting a 208 L oil drum FAE which was actually put to good use.

Yeah cooking your own explosives is like brewing your own beer in RL. it costs more than just going to the store for a 12 pack (in the case of explosives, your specialised contact), but, you do it right, and there are no "surprises".

I feel like clicking that link just put me on a watchlist.

Though I won't lie. Having a bomb-crafter on the team is very handy. PCs find themselves in high demand of explosions, and you don't always want to fiddle with availability rolls to make stuff blow up.
