I'm think this might be the Beetleborgs series.

My memory of the series is pretty cloudy, but the blue Beetleborg had a little sword type weapon (Stinger Blade), the red one had a gun-type weapon (Striker blaster), and the green one had a claw (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.
