Beeman P1 Trigger disconnect
« on: June 01, 2018, 08:48:37 AM »
Hi, I recently purchased a used Beeman P1 and after just a few shots, the trigger became disconnected and would not fire the gun.

The gun cocks normally, and I can put it on safe, but when I take it off safe to fire, the trigger pulls all the way back but the acts as if it has already been fired!

Is it possible that the trigger adjustment has slipped and now it does not make contact!

If I re-cock it hard, and push it closed hard, it will fire.

How do I properly check on the trigger adjustments, there are three?

It must be something small like this because it does not appear to have any broken parts.

Has anyone here had this problem?

I would appreciate any help that you can offer, this is very frustrating!

Thank you, regards, gkenny.

Have you checked to see if any pins have worked out?

Thanks for the response Cobalt327. No, all the pins appear in place.

This just happened as I was sighting I with my new BSA Red Dot for the first time.

That is why I expected that the trigger adjustment slipped, remember, the gun is used and I don't know where that last owner had the adjustments.

Thanks again, I really appreciate your help!

Regards, gkenny.

In case you don't have them, schematic and manual from PA:
https://www.pyramydair.com/model-schematic/555
https://cdn.pyramydair.com/site/manuals/Beeman-P1-P3-P11-Manual-low.pdf

The manual doesn't go into much detail with trigger adjustments, but it does say to turn the screw in to make the pull heavier.

This is how the shot cycle was described: "When the trigger is pulled, the primary sear must first fall, in turn releasing the secondary sear, which finally allows the main retaining bar and sear to fall and clear the piston, beginning the power phase of the shot". The reverse has to take place to recock it, so that may give some insight into what's the hang-up.

I'm wondering if there's a problem with the sear resetting. Have you tried manually pulling the trigger rearwards (opposite direction of firing) before cocking it? What about cocking the gun then manually pulling the trigger rearwards to see if the gun will fire normally? If either of these things seem to help I'd be looking at the sear

This has some info including a parts list that can be used to tell what the part names are on the PA drawing:

Good info if you can translate it from German! haha (photos of trigger parts may help):

The German link is from a thread here- https://www.gatewaytoairguns.org/GTA/index.php?topic=69620.0 it has something about a gun having similar problems, was a dry (no lube) situation where a link wasn't engaging properly or somesuch. Maybe you can make better sense of it.
