At what point in pistols life do you recommend changing out the sear spring? Is there a round count as with recoil springs?
Second, when it is changed, is it a drop in replacement or does it require fitting? Thanks in advance.
A quality aftermarket spring probably should never wear out. The spring simply is not under that much tension, and doesn't really move that much.
It requires fitting in the sense that it is a key part of trigger pull weight, and directly responsible for the grip safety tension. You will have to slightly bend each arm to get a safe and user friendly set up.

If you can Look for the new colt spring,
the return (disconector) and sear leaf's are thinned a little. Less inertia to deal with and maybe a little more responsive also. Personally I like the deep blued in color springs (colt). Also look out, there was a batch of springs circulating that had the center leaf short, they were around at the shows a year or so ago and caused some grief if you did not know any better.(they were matte in color iirc)
lastly yes the sear spring will directly affect the trigger pull, sear tension trigger return and smartness of the grip safety.
Just like the guys say.
Hi there O C! A sear spring can cause you to invent new words. Please don't fool with it unless the gun follows or doubles. There is much more to it than meets the eye.They last forever in a properly fitted pistol. I used to like Jim Clarks 4 finger spring until they shortened one of the legs. He said they still worked great when I called him so I just quit using them. The tension on each leg has to be compatible with the trigger job so I would leave it alone. I don't mess with my own and I have guns out there with 90,000 38 supers thru them that are still on the original spring.
