Pro package on SP01 still have 10lb DA

I don't feel like stripping it down all the way. Only polished with wet 1000 grit. Left machine marks as expected. Sides of trigger bar looks like a zebra!

Also check to see if the spring that lifts the trigger bar is riding in the slost underneath.  Sometimes it can bind between the trigger bar and frame.

Its in the right spot

When you keep the trigger depressed and manually rock the hammer back and forth, do you feel friction like drag on one side?

Also, if the hammer is indeed a bit canted/leaning, then the corner of one of the 'teeth' may be causing a lot of drag on the bottom side of the sear as it moves across.

Is this pistol new?  How many rounds total?

Under the sear cage on the pads that ride over the trigger bar should be polished as well. 

Nothing looks out of place.  I'm not sure what is causing the hammer wear but that doesn't seem normal.  Did your OEM hammer have the same wear?

Cheers,

So holding the trigger and running the hammer with my thumb has no friction and equal play left and right.

Pulling the trigger half way, the hammer has no play to the left and some to the right so as I suspected it's pushing the hammer a bit and dragging. But I can't see that being an additional 3lb

Is the hammer hole out of spec? Is the original hammer pivot pin out of spec? I'm using the hammer, both hammer pins, and disconnector from CGW and then the original strut and main pivot pin.

The underside of the sear cage is polished as well. Both the pads and the center where the disconnector can make contact and even the ledge on the back side that pushes on the disconnector arm. Not great but I did some there.

The gun has 500 rounds through it prior to the new parts based on what I shot and the PO told me (and based on wear he seems to be honest about it). None since as I'm trying to figure out this DA issue.

Put the old hammer and pins back in to see if there is a difference.

And the old hammer has some wear but on the opposite side the new one has.

As an update, I ordered a CGW "black" hammer spring and DA is now 7lb. So not sure why the blue one resulted in a 10lb DA when the advertised spring rate difference is only 1.5#

Whatever the issue is/was, I like the way its running now! The yellow recoil spring is nice too....

May want to try different types of ammo.  No big deal if you're only using for range or running Federal soft primers. Otherwise you may get some light primer strikes with different types of defensive ammo and black spring.

I have heard this may the hammer spring at the edge of light strikes. However I have been shooting matches with a guy running the exact same setup and he has not had any issues with his reloads and he runs several different primer brands he says.

I ran mine last night and it shot reman ammo great with normal looking firing pin divets (I am sure the longer firing pin and reduced power firing pin spring help of the pro package help with that). I have another reman brand to try as well as some MagTech and Hornady factory stuff I can test

Could have been an out of spec or damaged blue hammer spring.  Intereststing to try a different one in the same weight to if equally bad.
