tbaMUD Continued development of the CircleMUD core

I am looking for a better mod of the shotgun trigger written early in this very forum (which, incidentally, i modified for a fire extinguisher spray). Here is what I am looking for..

-The gun can be wielded.
-Various ammunition maximums
-Ability to insert NEW ammunition (ie. A reload command using an ammunition object)
-Optional: Specific ammunition for the gun in question

Once the basics are down, I can probably do some editting myself to arrange for different styles of gun.

Would it be aesthetically pleasing, and workable to just make a weapon, have it weilded, and set the weapon up normally. Then make a trigger that fires (some way or another) that describes the weapon as "firing"?

Just looking the best way, since my setting is modern.

HELP TRIG-EXAMPLES, specifically:
Weapons: TSTAT 1361, 9000, 11840, 13005
