the pumping of the pistol and the trigger have nothing to do with each other
one is front of the house and the other is back of the house
you state it fires and the only way it can fire is if the hammer hit the valve stem
but the term fires could mean different things to different people
now what we need are details
can you pump it up to 10 pumps without cocking the pistol and if so it is not the front of the house, meaning the valve
you cock the gun the hammer is held by the sear on the face of the hammer
the sear spring holds the sear up to do that and a much lighter than a factory spring can do that
but if the sear spring is so weak that you can shake the hammer from the sear as you cock it than the sear spring is too weak
this is not rocket science
@matchstickshooter I'm hoping that's the solve. Thanks there. My records and recall are lacking re. the barrage of mods I worked into The 1322 and BP2220 a decade ago. One of the two received an improved sear spring. I'll try stretching it out to some degree. Is it simple to "thumb out" freely or does it require some type of tension place holder at the top?
@marflow Yes.. I can fill it with ten pumps (with or without the safety) before charging the bolt chamber. I'll let ya. know if "de-improving" the sear spring squares it.
the Crosman sears have a certain amount of slop lets say, so they can twist
but i think you will find that the hammer spring is overpowering the sear spring you have installed and even if the safety was on the hammer could slam forward
the safety just blocks the trigger and nothing more
i have settle on the same spring for the 2240 or 13** if i leave the factory trigger group in place and then use a piece of pickup tube that are used in Dial Bodywash for the their pumps
and then a rivet with a resized head for the top of the spring
now there are more ways to do this, everyone has their own
now Magnum makes pins and sears
but as i said everyone has their own way

What I was getting at is a lot of owners cock the pistol, load a pellet and THEN pump it up.
If the trigger is light enough, at that point, couldn't it go off??
I bow out.............
yes, i agree Matchstick
if the sear spring is so weak that the movement of the gun allows the hammer to push be the sear engagement you have a problem
also a short spring might not have the sear at the right height
look it is a sear spring problem, you and i know these gun well enough to know that
too greedy equals malfunction
if it is twisting the trigger adjustment screw too far or to light of a spring in some sort of application
@matchstickshooter It's a top notch hitter again!!! After loosening the sear spring, tightening some screws and a good oiling, this show is back on the road!! Thanks to You both for the insights. Hooligan blue jays should not sleep well.
