Would you recommend the Grenade Launcher in Necromunda?

I like the idea of firing grenades everywhere, but am a bit concerned about the ammo roll.

Its for my Leader, who currently has a Bolt pistol and Sword. I would like her to have something with a greater range.

Also, my friend has the books, I cant remember what the launcher and frag grenades cost. I think it is 22 times the cost of a Sword?
