Need to work on/optimize the 1911 trigger. There are several commercially available options. Wondering which people prefer and why. Thanks

A Bullseye (or as they call it now, Precision Pistol) shooter here. By far the best sear jig is the TR jig, available at : Harrison Design

Depending on the length of the sear nose, I use various grit stones to remove the most of the metal, and then finish with a fine ceramic stone. There's a good post on the 1911forum explaining the process in details: https://forums.1911forum.com/showthread.php?t=335508 and there's also very good video on Youtube https://www.youtube.com/watch?v=Ks5Bbw3Z7lk (well, until the guy starts thumb cocking the hammer and ruining his fine trigger job )

Brownells sells inexpensive stone kits for sear jobs:

http://www.brownells.com/gunsmith-to...t-prod625.aspx
http://www.brownells.com/gunsmith-to...t-prod913.aspx

As for the hammer, usually it doesn't require much work, just polishing hooks carefully with a square Arkansas stone.

Also, often times the sear spring needs to be replaced, in order to get a smooth 3.5# pull. I personally prefer Cylinder and Slide springs: http://www.cylinder-slide.com/index....how&ref=CS0094

And don't forget to polish the disconnector surfaces and slightly stone the disconnector head.

I use a homemade TR jig. Works like a champ, idiot proof, provides a true neutral engagement.

I do the radius on the surface grinder.
I use the power custom jig for hammers and the relief on the sear.

Well yeah, there's always that way

If I had a surface grinder in my garage, that's the way I would do it as well!!
