I was wondering if someone could explain the process or point me in the right direction as to where to find instructions of adjusting the trigger of a 1970's era model 99 (with rotary magazine). Thanks in advance.

This is well documented in several of the more common home gunsmithing books - One of Roy? Dunlap's books comes to mind in particular. The Sav 99's also had a major change in their trigger design back in the 50's? I believe. Hope this helps Jeff P

Go to www.savageparts.com and use their exploded parts drawings to identify exactly which version of the M99 you have.
I have a M99EG from the 1950's. It was a simple procedure to clean-up and lighten the trigger on mine. Identify your version exactly and we can see if what I did will work for you

You simply shorten the sear that protrudes upward, not the opposite part that faces down...but be very carefull not to overdo it.You may also polish the opposing surfaces.

It is very easy to do if your skilled at hone work..You can use a file, grind stone to shorted it and finish with a hone. Keep it square...you can drill and tap a trigger stop in the lever and drill and tap a lock screw for the stop...again a simple operation, this will take out the large amount of overtravel in the Savage 99....I used to do a lot of trigger and accurizing on 99's but decided not to do that anymore.

learn to live with it as is, its not that bad after some practice...I can use any trigger as long as I know what its going to do.

Any trigger work will void any warranty and in the 99 can be dangerous when done improperly as they will certainly override the sear if you do just a smidgen to much, and they tend to wear..I suppose one could harden them, but I never did...
