tm g18 problem
 

so i got a extended mag with my g18c and when i insert it and try to pull the trigger it seems the trigger released but the hammer still has not released. i accidentlly pressed down on the slide and then the glock hammer releases. what problem is this and how do i fix it?

it seems it also has the same problem with the normal mags aswell

worn full auto sear. replace it.

checked it and it seems fine

I dont get how you're trigger "is released" if you're hammer is not functioning. If you're hammer cant be fired, your valve knocker can't actuate. Therefore no air passes to blow the slide back to trip the trigger bar for the reset.

The reason why you have to press the slide down to release the hammer is because the full auto sear is not being pressed. thus it hangs unto the hammer forever. So it's either worn or....

another issue is that the slide is being spaced apart either by the mag or the hammer bearing. if notice wobbling, this is probably the case. if this happens the slide cant trip the full auto sear.

i see im guessing its because of spacing issue between the slide and the frame. any way to fix this issue?

shim your BBU or wear down your mag catch. I reccommend the shimming.
Make sure you don't overdue it otherwise you'll misalign everything.

ok that might work question though what is a BBU and where can i locate it on my pistol?

Its the thing that holds your loading muzzle and your whole slide mechanism together. The fire selector. everything. Its under the rear sight. shim it. dont do the magazine catch thing lol. I dont know why i suggested that.

lol alright man ill see if it works

i also found a trigger timing problem where the hammer was pulled down before the trigger pin causing it to malfunction, also the lack of contact for the trigger pin due to the slide might also be it.... is there any way to fix the timing problem?

If you don't know what a BBU is perhaps you should get someone who is experienced in fixing GBB's to look at it.

LOL


I have 2 sets of PGCs and their quality is great. Hopefully they make some steel..

Anyways, I have 2 sets installed on TMs, and there had to be some modifications done to get everything smooth.

OP, did you install the conversion set yourself?

Try tightening down the phillips head screw under the BBU (Blow Back Unit), and the phillip head screw located on the frame located where the hammer is.

See if that works first.



Wait.

Is the extended mag a TM?
Have you tried other standard TM mags?

Has the gun worked before?

:rolleyes:

i actually bought it pre upgraded, yes the mag is tm, tried both standard mags before, no problem to that. and yes the gun worked when i got it in the mail, just recently while testing it developed the problem

UPDATE: partially fixed the problem and now the gun will shoot when the entire gun is faced in its default position, if i change the angle towards 90 degrees on all angle except downwards then the problem happens again :S MAN THESE THINGS ARE COMPLICATED!!!

and manually racking the slide can result in the problem for some reason as well :S
