need help with my kjw g23
 

my gun was working fine and i had only used it 2 or three times and than all of a sudan my gun was shooting but weaker and it wouldnt blow back for what ever reason. i cant figure out if its the mag or the trigger mechanism. its a kjw gbb glock 23 with a metal slide.

Have you tried a new propane tank? It may seem silly, but always try the simplest thing first.

ya i did i also tried green gas after and nothing changed
