Lighter Mainspring for 3913 or 4566?

[Zebulon]

I've been spoiled by the simple swap of a "D" Beretta Mainspring or the substitution of a lighter 1911 Spring to lighten the trigger pull of my Berettas. Is there a similar swap for the 3913 or the 4500 Series? Thanks very much.....Zebulon

I know two folks who swapped out mainsprings on 4566's. These were fun guns, for use on the range only.

The trigger pulls improved.....slightly, but reliable ignition became an issue with both of the pistols.

I would send my 4566 off to the Performance Center for a trigger job first, rather than risk compromising the superb reliability of either the 3913, or the 4566. My 0.02 Regards 18DAI.

Nope...Don't want reliability to become an issue. Thanks for the wise counsel 18DAI.....Zebulon

I've used the Wolff 18# hammer spring(long and short) in my S&Ws' with good results. I do change them out every few years for good measure.
