Please note that 0.01 is the default import scale in Unity, this is perfectly normal. When using Spine in the standard way, your export will be 1 pixel for 1 unit, where in Unity one unit is typically set to equal 1 meter. Thus a scale of 0.01 leads to 100 pixels being equal to 1 Unity unit (meter).
Note that Unity Sprite scale is also set to 100, which means 100 pixels per unit (100 PPU), which is the same as the spine-unity import scale of 0.01 (units per pixel).

Could you please provide more information about how you attach your weapon, and what your weapon is represented with (e.g. a separate GameObject with a Sprite)?
