Good morning everyone

So Stargate SG-1?

Same but with nukes

Apparently y'all haven't seen this show.

I need a double barrelled that can shoot three times without reloading...

This was even in the original Isekai; "A Connecticut Yankee in King Arthur's Court" (by Mark Twain himself all the way back in 1889)

Counter point

But he does have an OP power? Shooting 3 rounds out of a double barrel without reloading

Are there Isekais that take the protagonist to a modern setting? Rather than just a world of magic?

I just realized 'Army of Darkness' was an western Isekai..
