ok so my g18c's standard mag is not working properly, ive lubed it, took it apart, and nothing is changing?? i just want to know the cause of the issue??

the issue:

when i use the 49rnd long mag my g18 fires good and hard, full recoil, holds gas well annd can run all day with it! (minus the fact that i run out of bb's).

but my standard mag is weak, it has a hard time getting full recoil and will not last a full mag worth of bb's with a full fill of propane.

ps:

my g18c will only fire in full auto, im not sure why, ill be asking about that at a later date.(nothing looks broken or even worn)

the 49rnd mag is newer, the reg mag is stock. im not the first owner, but the origonal owner isnt sure either.
