Browning Buckmark Spring

some Time ago I did the "flip" on a spring I do not recall the name of it in order to "lighten" the trigger. Well the spring in now either broken and misshapen and I an having all sorts of failure to fires and some failures to feed.

Can someone in this forum point me in the right direction of the name of the spring/part# etc.

Thanks
