3 screw trigger

can a older flat back 110 be changed to the accutrigger thanks

Yes. But I think the 3 screw is a better trigger.

I too love the old 3 screw triggers. Really easy to adjust to, no creep, light enough, and crisp. When done correctly nothing more than a simple spring replacement made of piano wire from the hardware store leaving a nice arch in the spring, and a little tuning of a few screws and then locking them down again with nail polish.
The accutrigger is just a "lawyer" approved "user" adjustable.

You can send that old worthless 3 screw trigger my way!

thanks for the info will try to adjust the 3 screw

The best way to lighten the 3 screw trigger is to replace the heavy factory L shaped trigger spring with a smaller diameter wire. I used buzz bait wire to do mine. A $0.99 WalMart buzz bait will give two suitable wires. Just bend them like the factory wire.

BTW, not all early 110s had the 3 screw trigger. In the last years before adopting the AccuTrigger Savage only used the 3-screw trigger on varmint and tactical rifles. To tell if it is a 3-screw trigger look at the sear engagement. If there is a screw at the bottom of the sear shelf, then it is definitely a 3-screw trigger. If it does not have the sear screw, the wire replacement will make the trigger lighter, but won't eliminate trigger creep.
