Very nice.
Are these to be specific to a gun type (i.e. Annoying Arms Mk2 Auto-Rilfe), or just Auto-rifle?
Some other aspects:
A space that provides the overall + to hit for the weapons gear.
A space that provides the overall + to hit with weapons AND PC's bonus/skills.
A space for a secondary items' (grenade launcher) stats and ammunition mark-off
The weapon ranges (i.e. short/medium/long) and any specific +/- for that weapon.
For weight, I'd assume it would always be loaded at some point, so you really only care about the weight of the loaded weapon, and each mag/reload for it. Maybe put that behind the slash in the blank?
The weapon cost and ammo cost could be combined into a single entry, with the Cost/Reload, set up like the weight.
i like the idea of a couple of sentences for a weapon, giving it more character, and a reason to buy/avoid Uncle Albert's "sales"...
