Weapons are pistols, submachine guns (SMGs) and shotguns, as well as grenades. Melee combat "weapons" (empty hands, Hand Razors, Spurs) are also covered for the sake of comparison.
Each entry has a few bars at the top of it. The top bar features the name of the weapon (which includes the type of weapon it is), whether it's legal or Not, and the number of rounds it will hold per clip you load. Note that the Rounds/Clip figure is Not applicable for grenades (which do Not take clips and are always sold in sets of six), Nor is it applicable for the melee "weapons" discussed above (do I really need to explain that one?).
The second bar across the top of each entry has the ratings for Damage and Power. For a refresher on these two stats, check the Notes at the end of the combat section. The Damage rating is shown as it is represented in the pause screen: a bar graph on a scale of 0 to 10. I don't consider myself an ASCII artist by any stretch of the imagination, but the little graphs I provide should be clear eNough. After the bars is the verbal Damage rating seen when buying and selling weapons. After the Damage rating comes the weapon's Power rating, which is verbal only.
The last part of each entry has the sell/buy price schemes for each weapon, which stores you can buy them at, the in-game description, and my personal Notes.
