Things I liked: Cost, overall design, fits a wide range of guns.
Things I would have changed: For pellet/airsoft shooters, the ammo pouch is a little useless. I've taken to storing extra co2 canisters and filled 'magazines' (my gun uses a false magazine to store the c02 canister, which fits in these poutches). I wouldn't really bother changing this, but you're purchasing this for the extra pouch.
What others should know: I'll be the first to admit that it's a little tricky to figure out how it goes on, but once you get the hang of it, it's fine. For past reviewers, the dangling straps are meant to strap onto your belt/belt loops. It gives the holster much more stability. I'm considering purchasing another one for a dual holster on each side. For the price, there's really no reason not to. Also, just for reference, I've used a Walther NightHawk (stripped down of accessories) and it fits like a -dream-.
