KWA Glock 17 venting

[DomChat]

my kwa glock 17 causes the magazine to vent its gas after 1 or 2 shots , it is not a mag issue as i have tested a brand new mag .

Any idea on where the problems could lie ?

Cheers

Re: KWA Glock 17 venting

It could be:

Worn Mag Catch
Broken cylinder valve
Weak Hammer Spring
Damaged Connector
Damaged Hammer
Damaged Touch Breach (the flappy thing at the back of the BBU)
Damaged Cylinder

The list goes on. If you press gently up on the base of the mag whilst firing does it's performance improve?

When you remove the slide, place your thumb over the hammer and pull the trigger do you feel resistance if you let the hammer up slowly? Keep the trigger pressed as you do this.

Finally - Is it clean? what gas you using? Does it have a plastic or metal slide?
