> When I register the output, the energy deposit as well as the x and y position of the hits seem to be correct. This is not the case for the z coordinate. A clear excess of hits appears at the end of the gas-box volume in the z-coordinate (see attached plot together with the x and y distributions of the hits, which seem normal)

I would expect this excess at the end of the volume. Steps inside the volume are limited by physics processes and considerations about accurately simulating continues processes. However, every track leaving the volume has a step that ends precisely at the edge of the volume. So, I would expect that the last bin in your histogram has exactly as many entries as muon tracks that leave your sensitive volume. If none are stopped inside, this should correspond to the number of tracks you simulated.
