Umarex T4E HDR 68 Paintball Pistol Revolver

I picked up the .68 HDR from Hero yesterday, and I've given it a limited test with some training rounds. Here's what I like about it so far: -Open sights are bright white and make for easy target acquisition. -Simple to operate without any more moving parts than needed. -I really like the 'standby' (I don't know the manufacturer's term) setup for the CO2 cartridge; you can install a 12g cannister in the base of the handle, much like other CO2 guns, but this one is a bit different; it doesn't pierce the seal until you whack the bottom (think of the motion you'd make if you were inserting a mag into a mag-fed semi), at which point the CO2 indicator pin pops out at the back (it's red, which is helpful) to indicate that you're good to go. -It came with 3 magazines; 5-shot rotary mags that are easy to load and feel sturdy. -The construction appears to be mostly polymer, with some metal, but it doesn't detract from the build quality. -The Picatinny rail on the top, and short one on the bottom allow for easy mounting of optics or accessories (in the photo I've submitted, you can see the flashlight/laser I popped on the bottom). Things I would change to make it 5 stars (I didn't feel right giving it a 4, but I'd say it's a 4.5/5, just based on the following minor observations): -Larger than expected; I had purchased it for my teenaged daughter, and she found it too large/heavy to comfortably keep raised for a long time. That said, I didn't check the dimensions before I picked it up, so this isn't a flaw per se. Just something to keep in mind. -I would feel more comfortable if it had a manual safety, rather than the safety as it's described by the manufacturer (being the 2-stage trigger). No impact on performance, but again, something to be aware of, especially with respect to storage considerations. -On the last point, actually, since this gun is (by design) so simple to operate, it ought to be stored in the same safe manner as a firearm.
