This mod makes all guns in the game more accurate - and thus more useful in general. The mod reduces the overall crosshair size by half of the default for each weapon across the board. More significant reductions were made to the crosshair when running as well (crosshair reduced by two-thirds in these cases).
It should be noted that this was created on top of the unofficial patch by Wesp, so may not work correctly without it. That can be found here: https://www.moddb.com/mods/vtmb-unofficial-patch
To install, extract to your Bloodlines folder, under "\Vampire\" for the standard game, or "\Unofficial_Patch\" for the unofficial patch.
