The JS's performance and speculations

A longer barrel would should increase accuracy even at shorter range. IMO the JS barrel shouldn't be much longer then the MP5 at most 10mm or possibly te same, however if your compare the 2 design you would find then the JS is lighter and more compact.

JS: 450mm without silencer, 2kg (persume unloaded)
MP5: 660mm without silencer, 2.5kg unloaded

Well whit Uzi or mp5 I joust drop used magazine and insert other, without even lowering gun and eyes and manage to do it in maybe second and a half depending on a gun…
Now because weary compact design of JS magazine would be almost at my shoulder and I joust can see how I would manage to do it in such short time and without some distraction… I CQB that time and distraction can cost you life… Again I joust stating my doubts and I could be completely wrong because my limited experience …

Generally I agree with Isthvan that US type guns are easier and faster to change magazines. You can do it by using just your left hand, pressing the button to drop the used magazine and then insert a new one. But again, I think it's just a matter of habbit.

Comparing JS to AK47, JS can change magazine much faster. My limited experience is on AK47 only that I learnt shooting at some shooting range. When changing magazines on AK47, you need to release your right hand from the gun, press the lever to pull out the used magazine (you can then throw it away ) pick out a new one from your chest-pocket and insert it into the gun, then pull the XX (I don't know how to call it, the THING you pull to push bullet into the bore), everything's done with right hand. This is slow. I guess JS can do all the things with left hand. In real battle, when changing magazines, no matter which way you use, you must hide yourself up first, else it will surely cost you life.

when i looked at the pic of the js which have a removable handle bar, does type 95 have that option??

back on topic well true, but just wondering, is this weapon for only police and the military??

Well, the gun is certainly one of the shortest/most compact SMGs around, and also one of the lightest. (China has some of the lightest SMGs around. type 85 is only 1.9kg, but has a fragging bolt!)

The 5.8 variant can take on 50 rounds?!

Removable handle bar? I think that's just a variation/experiment. The gun isn't in real service yet. (And I hope it doesn't until the right death is solved.)

You can't really compare the JS to the AK-47 or the M-16. One is a SMG the other an assault rifle, almost all smg can reload faster then a assault rifles and I can't really name one then can't. Anyway is fairer to compare the Type 95 to the AK and M-16. The Type 95 an revolutionary for the PLA, it's a step aways from russian design. I can't really see much different with reloading a Type 05 and a FAMAS or SA80.

Back to topic: Don't they all have to pick out a new one from your chest-pocket and insert it into the gun, I though they do and from what you are saiding both the JS and US gun reload by using the left hand what the different.

A Yes and a NO. In real battle you find cover most of the time when you are reloading. Nevertheless there are time when u have to reload on the move and/or there a very limited cover around. Which the abitity to reload with one hand is a plus. However I really dun see any reason why you can't load the JS with one hand, and just as fast as the western counter-part.

I really dun think the PLA would want to keep their 5.8mm SMG round, moving on to the 9mm is a good idea. As it would provide a improve in performance.

What performance measures? "Performance" isn't just one number. The advantage of the 5.8mm pistol round is probably better penetration against soft body armor, while the 9mm probably has better stopping power and energy retained downrange. If I recall, the 9mm is offered to police, PAP, and export, while the 5.8mm is for military, if it is adopted.

SMG is use in CQB situation most the time, or i should said in situation which required CQB, which the 9mm is more suitable. There is a possibly that the 5.8mm have better penetration against SOFT body armor, but it doesn't have the stopping power. Prove me wrong if you can,
The JS is design for CQB, and 9mm is the better round for the role. Prove me wrong if u can!!

Geeze chill out. I don't have to prove anything to anyone. If you don't believe what I say, whoptie do.

The 9mm version is designed for police and PAP precisely because those organizations do not expect to be confronted with opponents with body armor (and logistically, the civies won't want to deal with another type of ammo unless they need to). The 5.8mm is designed for military because soft body armor is more likely to be encountered. I can dig up the article that says 5.8mm fired out of a Type 92 pistol can pierce soft body armor, but 1) I'm lazy and 2) just because you want proof, I'm not going to bother.

A pistol bullet is unlikely to penetrate hard body armor anyway, so shouting soft in bold is really a moot point. Besides, body armor will help stopping power, because it will help transfer more momentum to the target than having the bullet zip through flesh. Also, if I recall correctly, the 5.8 pistol round, like the 5.8 rifle round, has an air pocket to make tumbling happen earlier inside flesh. The PLA has adopted the 5.8mm pistol round, so they believe it fits their needs. Whether the PLA will use the JS, only time will tell.

It looks like the weapon suffers from a major flaw of Bullpup weapons; it is not ambedexterous. Unless everyone who will use this submachinegun is right handed, it might cause some compatability issues with some soliders. However, considering it's compact nature, it looks to be a reliable PDW and will come in handy for use by armor crews.

The Chang-Feng however looks to be a real stinker. If you think a bullpup design is dificult to load, Helical magazines are a real nightmare. Not to mention the bulky nature of the magazines causes problems with the storage of magazines on the body. (You could carry two MP5-style magazines back-to-back in a single pocket on the body without much bulk, but one Helical obviously will take up more space. Couple that with three or four, and weight becomes an issue)
