If a gun is added, then it would probably do a ton of damage, and be an almost instant hit(faster then the crossbow). Even if it did cost 95000 gold, some asshole would still buy it, and then spam the shit out of it. Only three shots=Three instant kills. It'd be like a shotgun, just hide around a corner, and when some guy walks around it, blast his punk ass. I'd say, make it cost 500000 gold, and then anyone who spends enough time to get that, deserves to use it.
