Trigger pulling the pump
 
When I slide the trigger, the pump handle slowly moves backwards, and it doesn't always fire. If I pull/hold the pump handle in the forward position it fires.

Is this normal or a problem?
Is this a spring issue?

Thanks.

this may help I ajusted pump rods and switched hammers to get mine to stop doing this

It's not an uncommon thing. Those links hold the best answers on how to deal with it.

I've often wondered if a lighter sear spring would solve this problem but since I keep a hand on the pump handle when playing I haven't been bothered by it enough to try.

I just tried changing the trigger pull and adjusting the pump/guide rod. That was the easiest suggestions to implement. I will check back with results.

I have tried everything that I am comfortable trying (adjusted the trigger a few times). When I pump quickly, the garg immediately fires without pulling the trigger. If I pump slowly, the garg does not fire, but the pump handle retracts with the trigger pull. I was hoping that one extra detail might help someone figure out this problem.

I am bringing my garg to Slim's game on Sunday. I don't want to interfere with anyone's playing time, but if someone wants to tech it, I would happily pay to have it right! It also has a slow leak near the 12 gram changer (it's still playable with the leak).

I'll be there, I can give it a shot

I can take a look if you catch me also.

Thank you Havoc and Greenmtnphantom!

No problem.

You can mess with the trigger more if you want. I didn't take the time to really fine tune it as my tastes would be different than yours but it's easy enough to change up if you want.

On the leak.

RTR Offers or did have shims that can be put behind the puncture pin. I saw you were using Lelands, they are great and I use them, they are very consistant in size but are a little shorter than some other brands. I'm guessing when it was reanno'd it took off just enough to cause your leak.

Thanks for fixing my gargoyle. To make this thread complete for future searches it appears that the pump handles moves with the trigger because the sear spring is stronger than the force necessary to pull the pump. The correction for this is a lighter sear spring.
The issue of the auto fire was corrected by moving the trigger forward so the sear didn't bump the trigger mechanism as the pump handle was pulled forward.
