Beretta CX4 trigger....any aftermarket ones?

So I just held a CX4 in 45acp. It was used and $479 with the top rail. Not bad, I like how it handles and my plan to chop the barrel and add a suppressor would go over well I think. But the trigger was like doing a pull up with my finger. Way too heavy. I know a SD firearm has different standards than target or sniper rifles, but that sucker was Heavy.

I don't see anything listen on Brownells, and a google search didn't turn up much.

Anybody?

Wow. I completely forgot about this thread.
Thanks for that link. Any idea how light you can safely get the trigger? 5 lbs would be great IMO.

Well, I don't mind the action making noise. I would just want the bang gone.
