Oh yes, all pistols are pairs and some weapons are a bunch of guns (like 10 muskets or 10 pistols) 
First, thank you for a great musket age mod. The American frontier is almost ideal setting for M&B style gameplay in the musket age.
The pistols pair is a bit odd. I can see the purpose of this, but personally not to my taste. Anyway:
Odd things the equipment. Some example:
- tricorn hats with 40+ armor (my sword actually bounced off a hat...).
- hair band with huge armor values
- Rifles appear rotated in inventory screen
- melee pistols? what is the purpose of that?
- hand axes with huge damage stats (38-40p)
- crushthrough flag on some irrelevant weapons (crushthrough only works with overhead strikes). Not a real problem though.
- A few native (warband, not american) items still appear in shops.
Character creation:
- I start with 42 strength and 25 agi. Is that intentional? If so it means that the only ability I will ever increase is int and I will swim in skill points. Starting with somewhat higher stats than typical in native is fine, but this is perhaps a bit overboard.
- I always start with Indian equipment. You can add another menu in character creation that asks for your origin. The selected option will set your cloths and perhaps the weapon (Euro or American native).
Skill names and associated weapons:
- Are muskets considered "crossbows"? in that case the skill name in the character screen should be renamed. It is a bit confusing.
- Pistols use the same skill a muskets? Why not use the firearms skill instead? Just enable it from the module.ini. If this is a problem of muskets and pistols sharing the same ammo then make them both firearms instead of both crossbows. I think that there are also a few differences in the core mechanics of firearms vs. crossbow skills.
Hunting:
- the boars have an indian face and they talk to me before I hunt them...
- they charge in once and then idle about until I kill them.
Village Bandits:
- villages are attacked by wild boars in the village infested by bandits quests...
The mod looks VERY promising, even though it is clearly still in development. Thank you for the effort!
