Maybe a duckfoot would be cool.

Gatling Gun
Would love to see a static Gatling Gun to replace the fabractor teir one something like this : https://en.wikipedia.org/wiki/File:Gatling_gun.jpg . This would present a good cheap RNG gun to fire a ton of bullets down range. Would love to see buildings with this on ready to fight a raid off.

Dutch Double barrel pistol
This is a nice two shot gun which would go well with the seven shot rifle. https://cdn.shopify.com/s/files/1/0760/6691/products/MVC-012F_4800f975-a957-4c2b-8f55-34b7e0f08081_large.JPG?v=1427324611

An interesting addition would be a bayonet. I have no idea if a custom melee animation with the musket thrusting with a bayonet would be possible, but it sure is fun to think about! I'm surprised an attachment like that hasn't been done in the game already.
Bowie knife and tomahawk would be darned welcome as well! :D Maybe even a cavalry saber or pirate-style cutlass. ;)
Possibly a full sized axe that can harvest wood even faster but require both hands. Get some real lumberjack stuff going haha.
Just some ideas for melee weapons.

This would be absolutely ridiculous, but if you want a REAL dino slayer, this would be it: http://www.thefirearmblog.com/blog/2009/02/22/more-2-bore-rifle-photos/
I also second the suggestion from Safe String with the howdah pistol. A very iconic English gun from India. Good tiger medicine!

A Winchester 1895 or 1886 would be nice

Great ideas! Winchester seems to be a most wanted

I actually kind of agree, I would rather have one of those over a flintlock pistol if a dinosaur charged me

What about a pepperbox pistol

neat little gun...an'all.. but IF one were really hunting anything like dinosars...well.. a pistol of ANY kind would only serve to piss'em off...no .. you'd need an elephant gun at least...if not an anti tank weapon...unless of course.. you'r talkin bout the little ones ...then the pepperbox might be handy

about the blunderbuss ...it was a favorite of pirates cause you could sweep the deck with it within ten to twenty yards ...it was loaded with any small bits of junk you could grab from nails to broken glass and was designed to spread quickly in a short distance knocking back and wounding as many as possible so others could finnish the job with swords and such..but it had no range at all...and it quickly fell out of favor when muzzel loading double barreled shot guns were perfected

I don't think you are considering it's use in pvp

well, if its 1800's them, then what about a 1893 Borchardt Pistol

I think there should be a field gun

A Winchester!A Winchester Pleeeeeeeeeeeeeeeeaaaaaaaaaaaaaaaassssssssssssseeeeeee
A Winchester

Can you please make a Winchester rifle!
