First things first: This pistol is plastic, pretty lightweight, shoots .50 cal paintballs instead of the normal .68 cal and is spring-fed to top it all off. All that added up generally means a subpar marker, which is what this thing is. Paintballs are soft and meant to break, meaning that they don't always work well when spring-fed. They warp and collapse under the pressure, and end up sticking to eachother. If you get one of these JT-50's, you'll probably wanna get a couple hundred reusable .50 caliber practice balls to use in your home, where it'll get most of it's use, instead of actual paintballs. If you do feed paintballs though this pistol, prepare to get a noticeable amount of that paint on your hands and cloths because this thing is very unforgiving of careless loading and shooting, and will chop paint left and right. I bought one for myself and another for a friend. This was about a month ago. The JT-50's about 10" lengthwise along the top, slightly under 12" overall size and a little over 1" thick. It's modeled externally after an actual 50 cal pistol in general shape and size, but with deliberate toy-like and practical design differences. For easy comparison, this pistol is almost the exact same size as a nerf maverick length-wise, height-wise, and in grip width. It comes with a very important black plastic piece in a plastic bag that snaps on and off of the top of the marker to close up the top-feeding hole when you take off the black scope-shaped hopper. DO NOT lose that plastic piece, you only get one, and if you lose it, you'll be forced to use the top-feeder from then on. I don't use the top-feeder anyways, the pistol looks and feels much nicer without it. I recommend only using the top-feeder if you've got ammo to spare, as it causes ball chops much more often and easily than the grip feed. Pro: - Firstly, it's double-action, AKA semi-auto. Most good markers are double-action, but there aren't many out there with this compact of a design for this little money. This is basically it's redeeming quality. - Gas efficient compared to normal .68 cal markers on the same stuff. Gets about 40-60 shots per 12 gram cartridge, and they don't seem to leak much if at all even when you leave the same cartridge in for days on end. I'll end up shooting maybe 20 paintballs and then taking it around unloaded to shoot people with bursts of air that can be felt over short distances. This can be both highly entertaining and terrible nuisance to people nearby. - For a functional semi-auto marker, it's relatively compact. It's light and compact enough to strap into an unoccupied vest pocket or even an elastic paint hauler loop, but i'd leave it in a drop leg holster since it's size makes it clumsy to draw quickly. As long as you don't use the top-feeder it'll fit into most full-size universal pistol holsters. - VERY easy to point and aim, thankfully. You end up just using the whole gun as a gauge to eyeball where your shots will go. Hands, eyes, and a brain all working together to aim this thing will do a much better job than the sights. - Honestly it just feels nice to handle even though it's plastic. The gun's not weighted but it's an okay plastic so it'll probably take some hits and maybe a couple drops. Feels nicer for bigger hands to hold, obviously. Only complaint is the black handle pieces both wobble around a lot, and the grip feed cover opens way too easily. - Could potentially be used in actual paintball games. Definitely not serious paintball, but you could still take it to a field, carry it around and score hits with it if they don't see or hear you coming. - Its comparatively quiet when shot next to my Spyder, so with some modification to further muffle it this could be used by someone seeking short-to-medium-range stealth shots. A woodsball sniper could put use to that as a secondary or last ditch pistol. Con: - Here's the big problem: Chops paint and double-feeds consistently if you load BOTH the grip and top feeders. Plan on using one or the other. If you load both, you must first finish shooting the top feeder, then switch to the grip feed. Problem is, the grip feed spring will very often push the paintballs past where they need to be and up into the top-feeder, causing them to get caught halfway and chop when you pull the trigger. - If you don't pull the trigger the whole way back enough to shoot, you'll end up lodging a ball into the barrel, but not firing it. The result of this is that the next time you pull the trigger, a SECOND ball gets pushed into the barrel, and if you manage to use enough force to pull the trigger then both will be fired at once. Two firing at once is not a good thing and should not happen. - Definitely more expensive than it should be. I'd pay 20, maybe 30 for this thing, not 40. - Trigger pull isn't bad when you use enough force, but it's definitely not a short pull, and pulling more than 3 or 4 times quickly becomes too taxing on the fingers. The trigger is most difficult right at the very end of the pull before the gas is released. This is because the force of the trigger pull is what indirectly feeds a ball snugly into the barrel, then puts CO2 behind it. Weaker fingers will have trouble firing over 2 rounds per second. - If you leave paintballs in it for too long or in conditions where the pistol gets knocked around more than it should, they'll sometimes get squished together too much by the feeding spring. If this happens, you'll chop EVERY ball. Either that, or it just won't even feed because they'll stay stuck together in one place along the feed tube - Tested with and without wind at varying ranged targets, and you're going to find that you generally need twice as many shots once a moderate breeze picks up unless you're within 20 feet of what you're shooting at. - Doesn't penetrate foliage well - The one build quality issue I really don't like is the grip feed toggle, which can actually spin, rotate outta place, and get stuck where it is if you leave it centered between on and off and mess with it. This is easily fixed if it ever happens by rotating the switch back into place where it came loose. Overall Rating: 3/5 If you don't care much about paintball or just want to get a friend something cool and cheap for a gift, this thing will definitely do the trick. It makes acceptable noise, feels very deliberate and easy to aim, and will last at least a couple months if you don't actively try to break it. If you don't mind neon green then this is the gun for you. It's a cool pistol to mess around with if you don't really care to play at referee'd fields and arenas or want to spend money on serious markers and paint. If mine ever breaks I'll probably end up getting another one, I've been having that much fun with it at least. If you do happen to play at organized fields and events more than once every few months, don't bother with this thing. It's 40 bucks worth of plastic than can coincidentally hurl non-standard paintballs.
