Easy Heavy Trigger Pull Fix

QuanLoi · 08-19-2012, 10:28 PM

My byf 42 Luger with all parts matching suffered from an unbelievably heavy trigger pull. The trigger pull was off the scale for every gauge I own and broke only when it reach the limit of travel. For me to fire the gun required a two hand grip with the index finger of my right hand on the trigger and the thumb of my left hand over my index finger both pulling at the same time.

The trigger plate on the left side of the gun has a lever whose horizontal portion fits into the fork of the trigger, which when pulled, moves the vertical portion of the lever and pushes it against the trigger bar plunger.

Now here's the fix: I mixed up a small batch of JB Weld and applied it to the top surface of the horizontal portion of the trigger lever - raising its surface (in my case) about a sixteenth of an inch. When the trigger is pulled the trigger fork comes in contact with the top (raised) portion of the trigger lever which increases the travel of the vertical portion of the lever that comes in contact with the trigger bar plunger. No heating of parts, no bending either. If for any reason you wish to remove the JB Weld, a razor or sharp chisel will slice it off.

It should be noted that a very small amount of JB Weld is necessary and the height gain on the lever should only be about 1/32 to 1/16 of an inch.

The result, in my case, is a trigger pull of five pounds.

(I hope I explained everything clearly...)
