Pekiti does, though I don't think many people are exposed to it. I saw just a bit of it at a seminar a couple of years ago. The emphasis was on close quarter shooting, this link shows the Pekiti firearm curricullum. http://www.pt-go.com/system_out_13.asp
All I saw was one or two of the gun seguidas, so I don't know what the rest is like. My instructor also incorporates close quarter shooting into his curricullum, but I don't think it came from Pekiti, but from some of his other training (he is a SWAT team member).
I defer to the wisdom of the late Hugh Bollers on this one.
"Boy, if you need a gun, carry two and a big Bowie knife. If you don't need to carry a gun at least have a .25 auto. And if you need a gun to go into that bar don't go into that bar."
Mr. Bollers didn't do any sort of martial arts, but he lived a very long life among people who didn't want him to.
