Insane trigger bounce HELP!

[Runamok]

I've played with a Mag and maintained my own for about 12 years. Just goes to show. When I air up my RT Pro valve it will fire when the trigger is released. Input pressure is 800 psi with a stock RT on/off. Then its " don't breath " because the trigger is that light, again stock on/off.Touch the trigger and she bounces like crazy. Now I seem to recall someone posting that the on/off pin length could be to short and cause this? I've replaced all the o-rings and lubed it well. If the pin is too short can I get a "longer" one? What length? And where? The "x/rt/ e" valve bounce I thought I had down pat , But this one baffles me . Any help would be appreciated.Thank you,

stock RT on/off pin is .750

stock RT on/off pin is .750

Ok I measured my pin it is .750. Any ideas as to how to solve this problem?

Check for wear on the sear and/or the bolt, or see about getting a longer on/off pin from AGD like a .765 pin.

Awesome But I've never seen a place for longer/shorter,?custom on off pins on airgun. What section is that in?

[Runamok]

On / Off pin

I found them on Tunamart . Now to help figure what length I need ; how much change does the extra length make? .750 vs. 60,65,70? I'd like to be able to pick the right length the first time and since it wouldn't be practicable to send my gun all over the country so you guys can play with the trigger can anyone give me like a "trigger pull" estimate for the different lengths?
Roughly?

Just get the 770 and keep taking .005 off untill it feels good.

That's easy for you guys with the big shiney machines. I don't believe the a hack saw or dremel will produce acceptable results.

is it shooting slow enough to feed paint into?

if not it could just be missing one of the orings up above the on/off.

I got to check that

[SR_matt]

that happened to me the first time i tried out my rt trigger... and second, 3rd and 4th times un til i realized i was not using all the pieces. i even tried shoting paint through it and it was going wayyyy to fast for my reloader b to even try and keep up

Check the condition of the on-off top orings and the condition of the sear assembly as well as the bolt lip. If the sear is rounded on the tip it could cause runaway/auto firing.

i used a dremel with a set of digital calipers with good results, just put it in a vice to hold.

Before changing the pin lenght, i would check the sear and bolt for wear.

Update on fixs
I checked the sear- it's in great shape nice sharp edge where it engages the bolt
Bolt- slight wear on the lip, but good condition otherwise. Normally I wouldn't expect it to be slipping off the sear.
On/Off top o-ring- Only one, I tried to do the double o-ring like a classic but the on/off assembly will not go all the way into the valve. It sticks out the thickness of the outer o-ring. took it out.
This valve is an RT Pro could it require a "Quad" ring like the E-mag valves?
Also when I air it up the on/off leaks slightly until I fire it 3or4 times.Then even light pressure on the trigger causes it to leak before it fires.
One odd thing I see occasionally is that even de-gassed the valve still keeps alittle air in the on/off which causes the pin to stick out even after holding trigger in to remove the valve. I have to loosen the body screw to disassemble the gun. Shouldn't it all vent when I de-gas it? could this be contributing to my woes?
I had a X-valve mag with ULT and LV 10 for years and never had any problems.

Thanks for all the advice I just wished I could find the problem.
Last thing to try is the longer pin, which if I thinking right will push the sear into the bolt engagement alittle more but should cause a longer trigger pull,?
