SA20 slam firing

[Sass20485]

My daughter has experienced her SA 20 firing when she release the bolt. Her finger was NOT on the trigger. I tried her gun and it did the same thing.

I striped it down fully cleaned it, found nothing broken. I am suspecting the firing pin spring may be too light and is overpowered by the force of the bolt closing, allowing the firing pin to protrude and strike the primer.

Anyone experienced this issue or changed the firing pin spring.

Thanks.

Sass, welcome to Mossberg Owners from E TN. We are really happy to have you with us.

The only reference to SA20 slam firing I found was from member @BrianJ about 3 years ago . He is still around. Maybe he can be of some help.

See reply 20 in this thread.

Sass, I found a couple of other pieces of info that may be of some help to you. Personally I know nothing about the SA-20, but it is nice that we have some sources that may be of some help to you.

One: Diagnosis of firearm problems thru internet exchanges can be a problem. Your problem is a definite safety issue. I would suggest contacting Mossberg directly.
I suggest contacting Joe Zakher at:
jzakher@maverickarms.com [ @old mossy - Is that still a good address?]

Two: I found another discussion on the forum you should read.
