Would it be possible to perform this mod completely externally with a small slab of nylon? This might be a better option for those who fear damaging their merker. (Complete speculation. None of this has been tested. Try at your own risk.)
1. Measure out exactly how far your trigger needs in both directions. Make sure your measurements are extremely accurate.
2.1 If the front of your trigger meets the frame at a right or acute angle...
- this trigger job will be more accurate.
- carve some nylon to fit both in front and behind the trigger and glue flush to the frame.
- allow for exactly enough room for the trigger to operate, plus some (based on how much jiggle you got
2.2 If the front of your trigger meets the frame at an obtuse angle...
- might be less accurate (with wear over time), but could reduce tourque and pressure on the actuating parts within the marker.
- simply place nylon to brace lower end of trigger only.
3. Carve to perfection.
- No modification to the marker at all.
- easily removed, rebuilt, reset (depending on how you mount the nylon)
- Easy, especially if you have a dremel tool.
- This requires that your trigger is extremely accurate itself. Any jiggle or wear will void this idea.
- After long term use, wear or slight warp within actuating parts might prove that the nylon is in the way. You could carve more or rebuild the nylon slabs without changing your gun at all.
- Might reduce finger movement.
But hey, it's an idea and I welcome anyone to try it, or use the idea to build upon further.
