I heard of one fella who did his own trigger job and much to his surprise the gun went off when in the safe mode, no one got hurt. Not saying you should use a competent smith but I'd be real careful and make sure you know what your doing. While it's not brain surgery it could be just a deadly if done improperly.

Very good advice .
Back when there were hardly any after market triggers we had to try and do something
with a poor trigger ourselves.
With luck we mad it better sometimes not much and other times we trashed them.
There is great difficulty in stoning the sear perfect by hand and if not done right you will ruin
it .Changing springs to lighten the pull can help but it won't make them break any smoother
just lighter.
If you are not experienced in trigger work I would recomend a good after market trigger for
the replacement.
No matter how much it cost , The safety margin is worth it. After spending lots of money
to make your rifle more accurate a good trigger will improve an already good shooter.
I am a do it your self person with experience in trigger work and I don't work on them any
more unless there is just not any after market triggers available.
