stats:

Pros:
- alt fire to double fire both barrels at once
- grenades explode on impact than have a timed delay
- this weapons reloads it's entire magazine at once

cons:
- 15% damage penalty
- 2 round magazine
- -15% reload speed

Fires 2 grenades at once
Grenades explode on impact
75% slower reload speed
-50% clip size
-50% explosion radius
-25% damage penalty

+30% damage ramp up
+10% damage
+50% reduced splash falloff
-50% clip size
-10% slower reload
-marked for death while reloading
-grenades fizzle instead of roll

bit gimmicky and weirdly balanced but i thought it would be cool :/

What I'd probably make this as a super shotgun from doom 2 but for demo because it sounds like a fun sub-class
Stats would be:

Shoots bullets instead of grenades
+25% damage
+25% ammo reserve
Fires and reloads both shells at once
-50% reload speed
-50% clip size

I'll update this if I think more into this

The Double-Tap
Level 1960 "Where's my grenade launcher!?!"

+ 25% Larger explosion radius.
+ 50% Faster firing speed.
- Grenades explode on contact with anything, (No roll at all)
- 66% Smaller clip size.

Demoman after he saw what Scout did to one of his grenade launchers: YOU TOOK MY GRENADE LAUNCHER AND YOU RUINED IT

The Ka-Boomstick
LVL ?? Grenade Launcher

(+) Fires and Reloads entire clip at once (Two grenades for the price of one trigger pull)
(+) Grenades Explode upon contact with surface(No Rollers)

This would greatly benefit both demo and/or demoknight.

Been a while since I've made stats for a weapon, but, here goes.

+50% Firing speed
+75% Projectile speed
+Grenades that bounce off walls deal mini-crit damage if hit directly

-Grenades have high bounce and roll
-15% Damage penalty
-30% Damage and explosion radius on non-direct hit explosions (rollers)
-50% Clip size
-10% Reload speed

This weapon reloads its entire clip at once.

+It fires 4 mini-cannonballs per shot that explode on impact.
+Faster firing speed and reload speed
-2 shots per clip
-smaller blast radius

So, each shot fires 4 small cannonballs. The entire clip has 2 shots. That makes 8 mini-cannonballs. That will be a lot of damage.
