Posted this on custom cockers about 7 yrs ago, probably had it posted here too before the crash.
Forgot I did it to more than just the Kapp frame. One user commented about using 2 washers would be better long term and I might go back and try it but both would need to be so thin it would take a while longer to do.
So this is an easy diy fix for any slop in hinge triggers that doesn't require permanent modding of the frame or trigger. I first did this to my KAPP hinge frame. I really like this frame and my only modifications to it would be to have a better fitting trigger, but that would be expensive. So if you want to make your KAPP frame have almost zero slop here is what you do.
Frames I have done:
KAPP 2x hinge frame: like butter now
Sterling hinge frame (very little slop anyways but now it's better)
Sheridan frame: Most difficult as I had to file the washer to half of its original size or slightly thinner. ZERO side to side movement...almost. unnecessary but it's now better than yours
Tools needed:
small hammer. I used a small monkey wrench so whatever works to hit the punch.
Punch for removing trigger pin
flat diamond file: I used the diamond side on my Leatherman Wave's file
brass washers from Lowe's or someplace: Cost less than $1.50 for 12.
How to:
Step one: remove hinge frame from gun for ease of work
Step two: slide the trigger all the way to one side to see how much space you need to fill with the brass washer. Check to make sure the brass washer won't fit before filing.
Step 3: steady the file against your workbench and hold the washer flat with your finger and slide it back and forth for a half minute or minute.
Step 4: check to see if it will slide btwn the trigger and frame. If not repeat step 3. If yes procede to step 5. It should slide in without forcing it otherise it will bind, but it can fit snugly and still allow the trigger to actuated properly. So test and retest. Take just a little off at a time once it starts to fit. You want the fit to be just past too snug where it will bind, but not so loose that you will have more slop than you need.
Step 5: Use your punch to back out your trigger pin so that it is flush with the side of the trigger. The idea is to keep your trigger and pin in the correct position but get the pin out of the way so you can slide your carefully fitted washer in place.
Step 6: use your punch to make sure the washer is lined up properly and then gently tap the trigger pin all the way back in.
Step 7: Test to make sure the trigger is free of binding otherwise disassemble and give a tiny bit more filing.
Step 8: revel in your now awesome feeling trigger.
Note: If you are so inclined you could file down two really thin washers and put one on either side of the trigger btwn the frame. This might be better but it would also require more work and be more difficult to do. If your trigger has a crazy amount of slop this might be the better way to do it. I'm thinking of you 2x finger Benchmark mag frame.
