Marushin Beretta m9 hammer

Hi
I got all gun assembled
BUT the hammer strikes very weak on the firing pin
Now connecting the hammer spring and the "push rod" into the hammer part have tested my patience and the problem might rest there - but I am not sure

does anyone the suggestions ?

Hello Christian,
I have assembled a lot of M9 but I never had this problem.
If your hammer is weak, it is surely a problem with the assembly. If all is ok the hammer spring is really hard, really hard to compress. The rod should be in this spring and the rod push the hammer toward the firing pin.
Like that I can't believe your hammer can be weak....Check your rod is well assembled against hammer.
It is possible to try the pressure of the hammer when you begin to assemble the gun : Just with hammer, rod(which is hammer spring strut) , hammer spring and hammer strut guide.

Let's us know if it's better.



ps: Not easy to explain especially without my best language....

Hi Momo, and others

worked on it last night Agree

All parts are fine

when metal spring housing in bottom of frame is out and only hammer and rod in all seems OK
I did find an edge on the inside of the gun frame, that the rod and/or spring might ride against

I did file some of the edge away and it seem to reduce the problem, but I guess i need to get a motor tool in there to get rid of all

have anyone encountered something similar ?

Sorry but I don't understand your problem and how you can reduce it... Maybe it's your spring housing that not push enough the hammer spring?
Sorry I can't see the problem without any photos.
I hope another real english man can help me because for me , not easy...

Salut Momocampo!
Il dit qu'il y a une bavure a l'arrière de la carcasse, qui gène la course du chien, et qu'il en a limé une partie, donc que ça passe un peu mieux, mais que c'est insuffisant et qu'il va essayer de finir à la dremel.
Si j'ai bien compris, bien sur.

Vous avez compris tres precis

next, important question is have anyone encountered same problem ?

The edge inside the frame is now completely gone - and so is the problem.

apparently the upper edge of main spring could be stopped by the edge.

I have grinded the edge and polished and the hammer now falls correct on the firing pin
