Hi James,
I used the Power Custom RUGER® 10/22® Pre-Travel Adjustable Hammer & Sear Kit, a Wolff Reduced Power 10/22 Spring kit,
TriggerShims.com standard Stainless Steel Shim Kit, and finished off with a Power Custom Aluminum Trigger on my 10/22T, ended up with a trigger pull that is very consistent at 1 lb 12 ozs.
All parts are easy to install for anybody using easy to follow instructions, and I think, IMHO, as good as any professional trigger job available.
A couple other items worth the money and worth mentioning are the Power Custom Stainless Steel Competition
Recoil Spring Guide, so smooth it makes the original guide rod feel like it was a piece of gritty sand paper, and a Tuffer Buffer recoil buffer.
All these parts are available through Brownells.com, except the
TriggerShims.com Brand Shim Kit, I manufacture and sell those, and I would be happy to send you one for free if you would like one. (send a e-mail with your address), no strings attached.
Good Shooting, Lance
