Great quality but 3 design negatives for Competitive Shooters. A) the foam is perfect for a 3.25" tactical or shorter pistols. Full size like 1911, 5" the barrel extends 2" past the foam. Also I compete with a SW-10 revolver with a 6" barrel. this has to sit and a very odd angle to barely fit. This leaves no foam protection on front sight tips. B) competitive shooters often use electronic ear pro; my ear pro barley fit as all pockets are nice but small. c) i wish the back of the pack had a sleeve for 8.5"x 11" paper extra targets, kinda like a laptop sleeve.
The rain fly is cool. there were many cool surprises like the rain fly and stuff that you don't see on the website. I would like an owners manual to help me understand intended use of the 40 plus different pockets/sleeves. Its very well made and balances gear weight very well. I am glad I bought it.

Update after a few trips to the range:
So far so good! Fits everything I needed and more and so easy to carry around. It's great to quickly see if I brought the guns I wanted before heading out and access them quickly while shooting. One tip when storing the guns in the slots: Try placing them upside down and they won't shift around as much when the backpack is upright. Also found that it keeps the longer pistols from sliding forward out of the slot.

Initial review:
So far, the backpack is very cool and does everything as described. It's really nice to have the ability to store 4-6 guns (4 full size and a couple subpacts) conveniently into the pack with room for all other range equipment. I do wish the foam gun holder was tighter to keep them from moving around but it offers adequate protection and is extremely convenient not having to put each gun into separate holsters or dig through the pack to access each one. The side pockets will fit a least 12 pistol mags with room for tools and small paper targets. The top compartment easily holds earmuffs boxes of ammo or if desired, a couple small pistols. When fully loaded up, the backpack is comfortable to wear without feeling much of the weight, hopefully the stitching holds up but only time and use will tell. Based on other reviews, I will avoid picking up the pack by the top handle but otherwise, the material and construction appears of good quality for the price point. I'm definitely happy with the purchase and can't wait to test it out in the field.

Pros so far:
- allows for more effective organization and access of at least 4 pistols from the main storage compartment. Longest barrel length that will fit is probably 5-6 inches, may not be flush but compartment will close just fine.
- enough overall storage for at least 12 pistol mags, rifle mags, misc range equip, targets, cleaning supplies, and if desired, two additional small pistols.
- quality of pack and zippers appears solid
- comfortable to wear even when fully loaded up
- good clean look
- molle straps for additonal storage

Cons: so far these are nitpicking as I have not had a chance to test durability or functionality
- space between each foam slots for each pistol seems too loose and could be tighter
- foam rack material appears a bit cheap and easily damaged or torn up.

When I received my back pack it look great in the package when I open and tried to get the zippers to move it was hard to open I almost broke one of the zipper trying to open it, also when I saw this backpack and what came with it, I notioce that I would also get a lock for it but it did not have one.

This is a well made bag. It is very versatile and secures my four firearms well. The deep well is very convient to carry ammo to the range. The zippers are also weather resistant which I was not expecting. Definately a 5 star. If I had to give any advise to maybe the next round of modifications for this, I would only modify the top handle. Seems kind of weak for the amount of load back pack can can carry. I suppose you would not be carrying it by the top if fully loaded but still feels weak compared how other top backpacks have.

I would buy this again in a heart beat.

Just received my backpack. Haven't tried them out yet. Seems to be built nicely and sturdy. It's got enough pockets built in magazine holder. Can't wait to try it out and fill it up with my guns. The only thing i didn't like was the strap that adjusts your backpack strap. It didn't have a stopper, so it wouldn't come completely off. I fixed that by just tying a knot at the end. Over all. It's a nice looking bag!! My friends paid more for their bags but i think mine looks better. Lol
