I have a bag that was issued to me in the military. I used to carry my handguns and ammo and muffs on my body before I got this, but now that I own this bag I couldnt be more happier. It took me 20 minutes to find it on google so you're practically obligated to buy it now lol. LBT Co. multi-cam Go Bag. This bag is very durable, has velcro all over the inside to attach anything you want or to provide a soft cushion for your handguns. The main zipper is extremely tough and well made. The buckle for the outside flap while plastic hasnt broke on me yet, I doubt youll ever break it unless you decide to use it for target practice. Its got magazine pouches on the outside for an AR-15, and everytime I take my AR out, my pistols are coming, so I like that feature. Its in multi cam, so it can be used in a tactical environment, and since its not black you wont have a hard time finding the contents on the bag.
I carry a 5 in. SIG 1911 and a Glock 19 in their holsetrs in my bag, with multiple magazine and ear muffs. The flap that goes over the exterior has a clear plastic liner on the inside, like an "admin poch". I put a notepad, sharpie, pens, and pencils in there. You could slide your phone and wallet into that flap also, so you can fit your mags in your pockets while on the range. You can fit a few boxes of ammo in there with all that, but truthfully it will get heavy. I carry all my ammo in a 5.56 ammo can, its a lot easier than trying to cram everything in that one bag. And since its a go bag, it can be used in that role. I have two of them so one is a go bag, and one is a range bag. I'm not sure of the MSRP for it since I got mine for free, but it seems to be around $60. I've used a backpack before and while they can hold more stuff, it sucks ass having to pull out everything to get to whatever is at the very bottom of the bag. Just be careful carrying both a Glock and 1911 in the same bag. It can be a dangerous combination.
