lightened triggers for S&W?

[5.0_CJ]

I have a beautiful S&W Model 645 .45 stainless... the only problem is the trigger is just absolutely asinine. It makes the accuracy of the gun impossible since your really bearing down on the trigger just to squeeze a round off. It's much heavier than the sigmas even. I've search but to no avail.. I'm looking for some sort of a new trigger for the gun to make it more realistic. Anyone have a suggestion?

I'd call Dave, the gunsmith, at Elk Castle. Or give a call to McClellands gunsmiths in Dallas. Either should be able to set you up with a solution.
