I just purchased a KMP9 from AirsoftGI and I'm having feeding issues with my magazine.

It seems like I'm having more jams in my magazine during the beginning of the mag then at the end of the mag. I think the springs too strong. Do I need to break it in or something? I tried lubing it but that didnt seem to work.

I'm using ICS .25g bbs.

The first thing I would try is different BB's.  Do you still have the BB's that the gun came with?  I would also get as much of the lube out as possible.  Lube attracts dirt and can make the feeding issue worse.  If trying different BB's doesn't work you may have a burr in the feed channel that needs to be removed.  Before jumping to a repair though try the BB's and let us know if that works.

I've found the issue, my bbs are getting stuck at the slot where the follower starts coming out in the mag.

Edit: I've found that my Matrix .23g bbs do not jam but the ICS .25gbbs do.

So, as I posted, it's a BB issue not a mag issue?

I had that same problem, the bbs get jammed up near the bottom of the mag. I lube the mag occasionally and I also make sure that the double stack is good near the bottom and I havent had any more problems

I had the same issue when I first bought the KMP9. The BBs end up getting squeeze that they are almost parallel to each other. I used Matrix & Golden Ball brand bbs. They have a softer shell so I tried the AirsoftGI bbs that I got & they work. The brand of bbs do matter. It seems the harder & more polished bbs seem to work for me. .20g is great but after I use them up, I'll got for a heavier bb. I also tries using silicone but that makes the cheaper BBs deteriate more. Might wanna clean any excess silicone too & make sure the mags R clean. I read that if U don't keep it clean, it also jams up. The butt plate came off mine so I had to send it to my local shop to screw it back in. U have to take the whole back internals to get access to the screws. The screws & butt plate looks stripped. KWA sells the screws but not the butt plate....

Try brand of bb's with a higher polish and slicker finish like KWA.  I would have to agree that your bb's may have too much surface friction to load smoothly.

Hey all. Just wanted to say cleaning the track on my mags solved this problem for me. Don't go through the hassle of tearing them apart to clean, just lock the spring down and use q-tips wet with alcohol to clean the track out. Also, make sure your bbs are staggered correctly and you'll be jam free in no time.

I had the same problem... it's not caused by bb the problem is that the spring is strong and if you don't do well the double stack in the whole mag you will have problems with any bb; even with aluminum bb or glass bb that are "perfect"
