Sharp Shooter Supply trigger is good, I have one on one of my rifles. You can also adjust and respring the stock trigger. It didn't achieve what I wanted, along with being safe, so I went the easy route and went with the SSS trigger. I'm sure other brands are good as well, but I can't vouch for them. I've had a timney on a Mauser, and it was good, but the results and ease of install would be model specific.
