Bonus video for the TTI G17
I mean, they are fine in the beginning, but they are two problems with the ZWK or we should just call them reskinned OY g18 at this point.
First problem is with this funky safety function under the main body. ZWK decided that putting a sliding switch in the area of the number plate is a good idea.
That thing will randomly rock back-and-forth and lock your trigger out and turning the whole thing into a brick with the slightest amount of vibration or impact. First week of only it gave me fear of breaking this four digit CNY investment.
second problem is that they constantly tried to remind you that you should not pre-cock the blaster without the battery on a.k.a. the magazine. They also mentioned you should only release the loaded spring with the mag on. I mean, I understand this is a field blaster meant to have maximum RPS out of a Glock body, but still, such design hurts my brain.
At this point, I’m not interested in playing any AEG Glocks anymore.

Mechanical electric pistols seem to be extremely fussy about getting all the motions right to prevent mechanical lock ups and damage.
I found the GBB Pistols more reliable purely through having much less mechanical parts having to work together perfectly in synch to function reliably.

The UDL P320 I got from Rok has been pretty good, the only issues I have is it gets really picky about the gels and the design of the follower doesn’t push the last gel into place to get picked up, and even the 2md to last gel doesn’t feed unless you flip it upside down, yet the slide lock will engage.
I haven’t sat down to look to see if I can fix this myself thou, it when it likes the gels its got some decent range and great accuracy and doesn’t care about being racked of dry fired with or without a mag.
They only other thing I can comment on which isn’t necessarily a design flaw is removing the pin to take the slide off is very hard, like everything HAS to be in the exact right spot to rotate the pin and take it out and just as difficult putting it back, like the tolerance of the parts is too exact.
Overall it’s a good little unit for cqb or as a backup.
QC problems, I think the sliding switch came with a weaker spring enough to lock the trigger, and yes with these OY Glock 18Cs/ZWD TTI G17, the spring can’t be released without the magazine. It is a different structure from OY G17/G34, this is why they have separate parts for each other, they are not swappable. Glocks under 2000 RMB have QC/structure problems, it is best to avoid a Glock EBBP, stick to a 2011 above 2000, maybe the QWK 2011. I know many rare exceptions for a good Glock EBBP, but they are above 2000
GBBs are mechanical, they win in reliability, electric is more complex, after the release of the piston, the motor needs to cycle the slide to lock the piston again, too close timing within each other and the piston will not return properly, and too far timing within each other and it will be a slow trigger response. Talking about the ZWD TTIG17, and the OY G18C, the motor’s RPM can’t be replaced, or else the full auto/binary timing will mess up, meaning no higher RPM, so you can’t replace it with a Chaoli 280 brushless
Not to mention, GBBs are easier to maintain in terms of disassembly, with electric, you have to engage the disassembly lever, then remove the rear slide cover, and then take it off from the front, and when you want to put the slide back on, there will definitely be a small metal piece you have to push down to slide the slide back on.
Yeah, I had the same issue with my UDL VP9. Must be a UDL design flaw. 
I ended up epoxy glueing a rubber block onto the end of the follower to extend it enough to put that last gel into battery while still allowing lockback on empty.
It worked, but did make filling the mag a little harder with the reduced aperture. I pulled it off in the end and just lived with the last gel sitting in the maglips, a bit like the gels left in the t piece of an AEG, I guess.

UDL doesn’t make VP9, are you talking about DX or DK?
Ah yeah, my bad… DK VP9 is what it is… bloody flu… 
Anyhoo, comparing it to Beemer’s UDL it looked like functionality and a lot of parts are almost identical. So good chance it shares a lot of commonality with DChapo’s P320.
The mags were cross compatible at any rate, so followers are likely to be identical.
That’s one huge slice of Heat Shrink!
Absolutely LOVE IT, even though it’s a Buzz Saw and not a Kerchunk Kerchunk!
Damn our stupid Government.
@Bart368 unfortunately those are Airsoft so even without the current border cock blocking we wouldn’t be able to get them anyways.
At least with the ones QQ posted they’re gel blasters so there was a >0 chance of getting them.
