Or at the very least, that gun that can beam bullets on DS9 should have been a lot more in-demand.
Both of those moments always remind me of the early DS9 novel 'fallen heroes' where Dax replicates a nasty Klingon machine gun to deal with energy weapon reflecting enemies. It also featured cultural dissonance for U.K. Readers, when toddler Molly burnt her 'fanny' on a radioactive deck plate. (It's a lot like any given Voyager episode that is time loop reset after everyone dies throughout the episode.) extra confusing because I think the writer had a welsh name. Took me right out of the book as a teen...I don't think I had even heard the American version of the word. Anyway, the energy reflecting faceless troopers taking over the station and the method for dealing them seemed very very similar to later Ds9 episodes.
