Sear Too High and Catching Hammer

OK, here's the gun I just got. Although it is not a pump, I hope it will be soon

Brand new and it very good shape. Except the barrel which is all scratched
up. It came stock with the carry case and no reg or ASA. I threw the other
stuff (barrel, reg, asa, hopper, tank) on just for the pic.

Unfortunately it has some problems firing. I think most are due to timing as
well as some small leaks in the pneumatics. Good thing I plan to throw a
pump kit on it, so all those problems will go away
Besides the pneumatics related issues there is also a slight annoyance with
the hammer and sear connection. It seems that the sear sits too high and
comes in contact with the body of the hammer. This allows it to "catch" on
more than one point.

Instead of ONLY catching on the hammer lug it can also catch on the
beveled hole around the hammer lug AND on the front face of the hammer
itself, that is how high up the sear is sitting!

Obviously this is going to cause some problems. Not only is the trigger pull
and cocking stroke choppy and inconsistent, it will fire at different velocities
depending on what point catches on the sear, because the mainspring is
compressed a different amount.

Is there any (easy) way to adjust how high the sear is protruding above the
top of the frame and into the body?

Adjust it like any cocker.

Stick 1/8" allen through the hole in the top of the body and turn.

Even with the hammer lug turned all the way so that it does not protrude
from the the hammer body at all the sear will still catch on 2 points. One is
the hole for the lug and the other is the front of the hammer body itself. I
don't think this is normal. I know that it does not happen on my 2k2 'Cocker.

I think grinding the sear may be my best option although not something I'm
really looking forward to. Pounding the pin out of such a thin frame doesn't
see all that appealing to me...

Which spring are you referring to?

I haven't actualy mess with those fockers to much but is there an adjustment for the trigger?? can you adjust how far foward it comes thus lowering the height of the sear and shortening the pull??

Hes most likely got the wrong trigger plate or sear in the frame. That or some type of "trigger job" was performed onit but someone who has no clue. Id pull out the frame guts and inspect everything.

I had the frame off and did not see any adjustment for trigger forward
travel. The only thing that stops it from going even more is the 4-way
connection rod. I did not see any place inside the frame that would be easy
to add an adjustable stop. I will try to get pics of the inside of the frame
tonight.

I don't think that changing the mainspring will change the points that the sear can catch the hammer.

The gun was won in some kind of contest several years ago and the owner
claimed to have never shot a ball through it. Based on the condition I would
tend to believe that. I definitely don't think he had the frame off.

I will take it apart again tonight and try to take some pictures. I think that
my "last resort" of grinding the sear may be my best bet.
