with my 36" condor double rifle (again same style as the drago/voodoo/etc), i carry:
my 15-22 in 1 of the main rifle pockets
mags, targets, etc in the 2nd rifle pocket
1911 .22 and xd9 in the 2 handgun pouches
tools, spare parts and accessories in the pocket in front of the handgun pouches
safety glasses and ear muffs in the large middle attached pouch
paintball pod with 400 rds and 2 15-22 mags in each of the 2 medium outer pouches
and i could probably fit more stuff in if i wanted to drag it everywhere.
ive got the drago double rifle case 36" bag in tan and love it! Fits my 15-22 and my 15 sport along with my 1911, g17 and ammo,mags, hearing and eye protection, lvl 1 first aid kit, cleaning kit and targets.
Freedom, yes I carry two handguns in the pouches inside the front zipper, Browning Buckmark .22 and and Ruger P85 9mm. No issues, as others have noted the front pouches then allow you to carry eyes / ears, mags and ammo. You will have plenty of room. You can cram more stuff in there but they you have to carry it all.
As w0ady said the Drago and Voodoo are both good bags. I looked at both and found the better price on the Drago.
Good luck. If you want pictures of the inside pouches let me know.
Have you tried shotguns yet? I know there are collapsible stocks and what not. Shotgun might be my next gun purchase is why. So i can hold that with the 15/22. I'm guessing the 42" will for sure.
