MacG22, 1++ on your great comments and I agree with all.
I'm still kicking it around about springing for another checked bag. If not, will probably take my EDC, holster, its alternate barrel and some SD ammo. Have been intending to try some of the ranges in FL but also wanted to have more than one gun.
If I have any further dialog with Allegiant, I'll be sure to post it. Will add that they were nothing but nice, courteous and helpful as they could be to me even as I pressed the issue on their regs being so ambiguous and unclear. But, they held their ground.
Thanks again for all your help in this thread.
