[Star Wars] Has there ever been a Force trained gunslinger?

I don't mean people who may have some small degree of force sensitivity, I mean a full Jedi/Sith level trained Force user who uses blasters as their main weapon. Hell, lightsabers come in many forms, like the lightsaber whips, so kyber crystal blasters seem well within the realms of possibility. 

I would think that the variety of abilities that skilled Force users have would make them godlike marksmen, if maybe not as effective in a fight with another Jedi/Sith.

In Coruscant Nights novels, one of supporting characters was a so-called "Grey Paladin", member of a small sect that broke off the Jedi Order over their reluctance to rely on the Force and Lightsaber. As a result they largely use their Force powers to enhance their marksmanship and are pretty much Force Gunslingers.
