Of course, I have 2 points in Fire Arms, the gun... it requires 3.

My Fire Arms is 5 and I'm still using that gun.
I have something else, but ammo is a bit more scarce... >.>

I've watched three let's plays and on my own game, the flintlock pistol has been every time in the first dungeon. But hmm I think we all had an alchemist in the group, so maybe it's a class dependent drop..

edit: or maybe we all had firearms at 1 in the beginning..

Out of curiosity, what did you find in the wooden box in the first dungeon?
