Weihrauch HW100 T has become completely inaccurate

[jepho]

It looks as if I may have an answer. I retrieved my gun today and had an examination of the gun visually and just slowly worked the cocking lever.

When the cocking lever is taken through its range of movement (that is just letting it spring open only) and then the cocking lever is closed... everything appears to be normal and the lever moves smoothly through its whole range.

When the lever is used to actually cock the weapon, as it is moved forward to a position just before it is fully closed, the lever snags very slightly on a sprung button. Very slow motion action shows that the snagging causes the probe to move and raise very slightly.

The sprung button is the hammer securing bolt. A hammer bolt plate and hammer securing bolt spring are a part of the assembly along with a couple of hammer bolt plate screws.

The part numbers are 2633, 2634, 2635 and 2636 from John Knibbs's catalogue.
