Wolf GP100 reduced hammer spring makes the start of the pull feel “clunky”

[bripro]

With the standard factory hammer spring the trigger might be heavy but is smooth. When I install any of the three various weight hammer springs that came in the wolf kit the start of the pull has this weird little jerk or clunk before smoothing out.
I don’t know if it’s because the top of the springs are still round and not flattened out?
Whatever it is it’s annoying enough that I put the factory spring back in and unless the forum has a suggestion I just paid 17 bucks for a trigger return spring.
Any ideas would be appreciated and yes all contact points are smooth, Brian

Watching this with interest. I've noticed a bump when pulling the trigger on a few Ruger double actions.
Attribute it to the cylinder latch engaging. Seems to work out somewhat with use.
