Thanks edster48! I definitely want to check out the open shoot this Saturday. Do you know if I have to sign up for this open shoot? Are there required equipment for the open shoot? I have a sling for my AR and an OWB holster for my pistol.
Inspector Thank you for the Sunday meeting invitation, I would love to meet up sometime and see some classics in action! 
hdf range days are the last saturday of every month on the hanauma bay corner of the range
look for all the cars and people near the white container
you do not have to sign up for open shoot
all legal firearms in hi may be used
people bring shotguns, rifles, and handguns
10 round limit in the magazines, though
classes are limited, and the signups occur on the second saturday of the month at 8 am
classes have required gear, for open shoot, you run what you brung
no shoulder holsters or iwb
