I have found my 2100 to be incredibly accurate with the right pellet, RWS Super Domes for me. The trigger left a lot to be desired, a long gritty pull.The trigger pull was so long I could lose concentration waiting for the trigger to break. During a fit of boredom I tore into it to see what could be done... I did the usual, polish all the contact points and a little moly on the pivot and contact points got rid of the gritty feel but didn't help the long pull. To keep from having to remove the barrel and pump tube from the reciever half I removed the sear spring and the sear pivot pin and was able to remove the sear without disturbing the rest of the AG. I was able to cock the hammer and pull the trigger with the gun opened up and could see the sear in action as I pulled the trigger. The sear moves in an arc as you pull the trigger and actually compresses the hammer spring slightly before the sear releases the hammer. I figured if I shortened the sear it would shorten the trigger pull and possibly lighten the pull weight some. Needless to say I was a little spooked about changing the sear shape because of all the warnings I've read about doing this, then I remembered Crosman sells replacment parts for this AG and if I screw it up I can replace it :D
Using some 400 wet/dry sand paper on top of my hone for a flat surface. I took the point off the sear shortening it .010" at a time (taking care to keep the sear perpendicular to my sandpaper) then reinstalling it to check my progress. I found a big improvment at .030" shorter and stoped there until I could get a spare sear from Crosman in case I took it too far and made the gun unsafe or unshootable. With a spare sear on hand I continued, taking .010" off finally stopping after removing a total of .050" I now have a much shorter, smoother and predictable trigger. When I was happy with the trigger pull length I did a final polish on the sear with my hone to remove any scratches left by the sand paper.
Besides needing three hands to put this AG back together if you take the barrel and pump tube out of the reciever (I got lucky and everything stayed in place while I was doing this mod:thumb:) this is a fairly easy mod to do.
One thing to watch for during reassembly is that the sear spring ends up in the right spot and doesn't get crushed between the 2 halves when you close everything up ( See the last Pic)
I'll close with the usual " do this at your own risk" and" if you screw up your air rifle it's not my fault" comments. And a couple pic's to help you see what was done....
