I've been using the I-shot Gurkha backpack. The overall design is very nice. Several different zippered compartments make hauling your gear to the range or match very easy. The lower front compartment is perfect for your mags, and the compartment just behind it, works well for spare parts and range tools. There is a removal Velcro pouch in the main compartment that holds two pistols. Plus, there is handy little compartment located on the lower backside of the bag which holds your ammunition. Overall, I'm impressed with the design of the bag, but... after you put your eyes, ears, timer, and any other equipment you may need at the range, the bag becomes extremely full. I really like lugging my equipment in a backpack, but it would've been nice if it was a bit larger.
