I'm think this might be the [Beetleborgs](https://en.wikipedia.org/wiki/Big_Bad_Beetleborgs) series.

My memory of the series is pretty cloudy, but the blue Beetleborg had a little sword type weapon ([Stinger Blade](https://metalheroes.fandom.com/wiki/Stinger_Blade_(Beetleborgs))), the red one had a gun-type weapon ([Striker blaster](https://metalheroes.fandom.com/wiki/Striker_Blaster)), and the green one had a claw ([Hunter claw](https://metalheroes.fandom.com/wiki/Hunter_Claw)).  

I'm not sure how well this fits.  I don't think they were cops (though their visors  remind me of Robocop), and I'm not sure if their weapons talked.  They had a bunch of technology though, so that wouldn't really surprise me.

This seems like a bit of a wild guess; just the blue guy with a sword and red one with a gun, along with the power rangers-like style made me think of this series.
