KWA Spare Magazine for KMP9 Airsoft GBB SMG (Type: 48rd / Long)

"They work. If you use green gas or a metal propane adapter, you will cut the seal if you do not have it straight. They can leak after a while if you do not keep a bit of gas in the mags. KWA is good for getting parts in quickly so it isn't the worst deal if something breaks.

"Super sturdy mag.

pros: NO LEAKS
ALL METAL
FITS IN UMP 40 POUCHES
HOLDS GOOD AMOUNT OF ROUNDS


cons: out of stock often

"So i purchased these mags with my kmp9 about a month ago, they are VERY high quality and good mags.
PROS:
-Metal, very durable
-great gas efficiency with the NS2 system (around 2 maybe more mags with one fill)
-48 rounds
CONS:
-a bit on the heavy side, not too bad
-expensive (normal for all gbb mags)

"i bought this from evike at the recent airsoftcon. I waited in line for probably 2 hours to get one. What i can say is that its amazing. The gun performs very well. its super high quality polymer. Everything else just feels really good about it.

Pros
feels really good
high quality
loud
mags are metal
i got a picture at the KWA booth when i bought their product and now its on their web page!!!!
The mags hold gas very well. I went through a mag on full auto and still had gas left over for half a mag for the second reloading

Cons
stock wobbles
Thats all i can think of that's bad about this gun.

"Great mags work real well these mags are made for the kwa mp9 by kwa so no worrys you are getting your moneys worth

"does this work with the kwa mp9?????????????????????????????????????????????????????????-
?????????

"Good overall with some small flaws. These mags hold a good amount of BBs and a lot of gas; 2-3 mags worth of semi automatic firing at room temp. They are also very durable and parts are readily available from KWA themselves. The flaws are that they are heavy, don't fit into many pouches, and the biggest issue is the exposed BB track. This is good for loading BBs and for checking remaining mag capacity mid fight, BUT if you drop them in sand or dirt one time, it can ruin the their ability to feed permanently. The sand and dirt will essentially scratch up the smooth surface finish inside the BB track if you don't immediately disassemble and clean the mag with rubbing alcohol and silicone. This will cause the BB follower to just get stuck in place toward the top/end of the mag when spring tension is low and it sometimes will not overcome the new rough inner surface. Overall good product but I wish they had an enclosed BB track to keep the loaded BBs clean and maintain smooth feeding capabilities in dirty situations.

"Yes. These mags work for the KWA MP9. My team picked up a total of 8 of these particular mags from here on Evike. Had some feeding issues in the beginning with EVERY mag, but we realized the mag slide had to be cleaned out and lubed slightly for them to work correctly, or else you'll only get off 1-3 shots before you run into feeding issues.

Pros: extra 50 rounds, and holds gas well and without leakage, once cleaned and lubed- these mags perform flawlessly
Cons: mags come dirty right out of the box. must be cleaned and lubed to prevent feeding issues
