Fairly modern, compared to the old greasegun I got into one of my first shootemups with. They make a poor rifle substitute.
I hope the orcs in your novel meet up with a crabby old leftover troop with one of Gordy Ingram's finest in his hot little hands. They will do the job just fine.
I see that John Ross' second effort will be coming out sometime next year as well. I hope your efforts don't directly compete with each other.
