I have Octane 45HD which right now only have .578 x piston adapter. I have the Gemtech 9 with 1/2 x 28, I have the Grunt -M for 5.56/.223 barrels and an HA Guardian .22 can. I have a private place to shoot and of course the M11/9. I live off exit 212 on I75 and the place I go shoot is down off exit 201. If you can catch me at home I will be more than happy to take you shooting. Just ask @AirOpsMgr or @Red Dawn and they can let you know. I can do a range near by or Charlie Elliot.
