Sear spring floated on me?

[txgho1911]

I am working on adding a wee lil bit of tension to the ejector- no extractor in my SA 5" loaded and I attempt a funtion test.
I hold the hammer as I usualy do to let it down. It falls under spring power only half way!
I only had the slide off the frame as I am working on the extractor and never pulled the trigger/safety group apart.
Going to see a local mechanic for a smiths checkout but wanted to pose this delima for any coment or explanation.
I didassembled and braught it all back together in working order. I just can't trust it right now.

I think you are working on the extractor, not the ejector from the sounds of it..

I would guess your problem is a mainspring housing full of crud, or with a burr in it if the gun is fairly new.

Pop the mainspring housing out, and compress the plunger all the way down and back up slowly, see if you can feel anything not quite right. It should operate smoothly. If you do feel something push down on the plunger about a quarter inch and push out the little pin that captures the plunger, let it up slowly and keep control of it. Remove plunger and spring, see if you see anything odd. Clean well, a light coat of FP10 or something like it on the spring, plunger and spring bore in the housing. Reassemble and test again.

Another thought..

When you let the hammer down and it only went part way under spring pressure, was the hammer loose to swing back and forth or did it stop firmly?

If it was loose the above post is valid, if it was stopped firmly it was probably caught on the half-cock notch.

I meant extractor and mainspring housing was pulled and resettled.
And it was loose way back away from the half cock. Lets say 50% travel on the arch.
I have the original MSH that has that new fangled ILS (integral locking system) and a close look at that tells me it may not be completely vert in key alignment. Time to figure out is I wanted a bowed or straight checkered replacement. Your note of stopped or free made it click in my head. Hammer strut has 0 spring pressure there for it's a MSH clew (as Tuner might say?).
I think the sear spring has taken some wear also as it looked bent hard at the base of the three way split.

I realy need to land this thing in the right shop. So far I'll get it down to Scroggins in Martinsville, In by the weekend.
