Savage 110 Trigger
Adjustment of the Savage 110 Series TriggerThis is great info that I pulled from the web. The author is Ken Russo
Before we begin, you should understand that the Savage Factory Trigger in 110 series rifles is a simple yet effective trigger capable of holding a setting to about three
pounds. It has adjustments for lightness of pull, trigger creep, over travel and safety engagement. The Savage trigger should not be stoned, or filed down at the sear
in order to reduce the pull weight. Lubricating the sear with a dry moly powder and dry firing the rifle 40-50 times will smooth out (break-in) the sear and provide
smoother function. Savage rifles can be dry-fired without any adverse effect on the rifles.
Those desiring a lighter trigger than three pounds should consider a good after market trigger like the Sharp Shooter’s Supply or Rifle-Basix triggers. Adjustment of
triggers should only be performed by mechanically inclined individuals who have a good understanding of mechanics and more than your average dose of common
sense. It is important to keep in mind that setting a trigger too lightly can and most often does result in accidental discharges and slam fires (round discharged from
closing the bolt on a live round) as well as safety induced discharges from improper trigger adjustments. Use caution in following these directions and never use live
ammunition to test the function of any rifle’s safely mechanism. I was lucky enough to attend the Savage Law Enforcement Armorer’s School and think these
directions are easy enough to follow safely. Use Lock-Tite thread locker in order to secure any adjustments made to your rifles trigger mechanism. Anyone who has
any reservations about making these adjustments should seek the assistance of a qualified gunsmith. The small amount of money you’ll pay a quality gunsmith for this
service is well worth the peace of mind in that you’ll have a safe rifle.
This is a small diagram of the Savage model 110 Series (which includes 10/12 type short action rifles and 110/112 long action rifles) trigger group.
Steps to follow:
1) Remove the rifle from the stock by removing the action screws in front of and behind the trigger guard.
2) Minor adjustments to weight of trigger pull can be made by adjusting the tension on the trigger spring with Screw #5. Remember to keep some pressure on this
spring in order to insure proper function. Setting the spring to lightly can prevent proper trigger recovery/re-engagement. Make sure the spring rests in one of the
opposing notches in the screw head to secure the adjustment.
3) Screw #1 is to adjust the smooth travel of the safety lever. The safety lever should have no up/down (play) movement. It is also important to understand that this
adjustment is usually not often necessary, but require the trigger be removed from the action in order to access the top of the screw.
4) Screw #2 should be loosened with the bolt cocked. Turn to loosen until the sear releases. To re-set the sear engagement, you must turn the screw back in a
minimum of 1/2 turn. The minimum safe sear engagement is .015”. Once this is achieved, re-cock the action and adjust the safety screw.
5) Adjustment of the safety screw should be done with the safety “ON”. Adjust the safety screw to slightly touch the safety bar but not interfere with it’s operation.
The rifle’s safety should be tested wile unloaded and while aggressively cocking the bolt handle and also bumping the rifle butt on the floor to attempt to make
the rifle dry fire. Perform this with the safety on and off. If the rifle does not pass this test, re-check your safety adjustment and sear engagement settings.
6) To set the trigger for overtravel, turn screw #4 with the bolt un-cocked.
DO NOT ATTEMPT TO SET THE SAVAGE FACTORY TRIGGER BELOW THREE POUNDS. SLAM FIRES AND OTHER TYPES OF ACCIDENTAL
DISCHARGES ARE PROBABLE IF THIS GENERAL RULE IS IGNORED.
7) Use lock-tite to set all of the screws adjusted in your project. Use dry lube (moly-powder) on the sear for lubrication and dry fire the rifle to break in the setting
and get used to the new lighter pull weight. Never point a rifle towards anyone. treat all weapons as if they are loaded.
ADJUSTING THE SAVAGE TRIGGER
by Claude GatewoodNOTE: These procedures are to be used at your own risk. Adjusting a trigger is a serious and potentially dangerous activity. It should only be performed by qualified gunsmiths. If you decide to adjust your own trigger, you do so at your own risk with no liability from the author or the website operators. In any event, please be safe and triple check the operation after any modifications.
This is how Savage trigger work is performed in my shop. Using this method its fairly easy to get a 2 pound safe pull with little or no creep and reduced overtravel. You will need a vice, a diamond stone, a spring steel wire that measures .040 (replace the .055-.060 factory wire) Pliers to bend the wire. Moly or synthetic grease. Unload gun, take stock off set. I clamp the end of the barrel into a padded vice to hold it while working on the trigger. Remove the “c” clip that holds the trigger pin in. Set the factory wire aside. STUDY THE MECHANISM TO UNDERSTAND THE RELATIONSHIP OF THE PARTS. You will be taking the trigger apart and putting it back together often- get used to it. Check your work often, this way you won’t be calling Savage, or me!
This first photo shows the first point we will start working on. The upper end of the sear closest to the pencil is where metal needs to be removed to reduce the “creep” or slack felt before the firing pin falls.
The next photo shows me using the diamond file to gently file off the metal from the top of the sear. Take about 5 strokes from the top (look for the bluing removed to keep it even) and reassemble check to see how much metal was removed. The final amount won’t be all that much, so go slow. This photo shows the relation of the stone and sear.
Next we clean up the face of the sear, this geometry is CRITICAL to the pull and safety, you must have a slight positive relation. Look at the face of the sear under light and you’ll note the bluing removed make sure this is even and square. Again, a couple of strokes at a time. Reassemble and test with the factory spring.This pic shows the relation of the stone and sear face.
This will reduce the pull but go slowly. Constantly reassemble and test your work.
Now we are going to work on the infamous Savage boltstop/sear combo. This is going to be stoned at a 90-degree angle to receiver. Note the bluing removed to maintain an even cut. You will want the geometry relationship nearly neutral. The red stone fits neatly up inside to stone this area.
Reassemble the entire trigger assembly and install the new .040 wire spring (cut and bend it to match the factory unit)
Pencil point shows the screw that controls the pull weight. Make absolutely certain the wire is tightened enough to hold a constant pressure on the trigger shoe. This is where a great number of trigger jobs go bad. The person backs out the spring to a light pull the spring MUST hold tension to work. The reason for the light wire is so you can have suitable tension on the trigger shoe. A stiff wire barely resting on the tension screw will go off unexpectedly.
This is the overtravel screw. Screw it in gently until it stops, cock the rifle and unscrew it until it fires. Add a ½ turn more. At this point test your work, cock the gun, cycle the bolt vigorously. Make certain it stays cocked. If it wont stay cocked increase the tension screw. If you feel “creep” go back in and restone the trigger sear (tip; use a black magic marker, work the assembled trigger and look to see where its rubbed off, make sure its even, if you see a “hitch” or uneven wear, use the stone). This is easier than it looks. Finally don’t panic if it’s still heavy, study the relationship of the sears, and remember we want a nearly neutral engagement.
Ok, now we are getting down to the wire and need to final check everything. This pic shows the safety adjustment screw. Cock the gun, apply the safety, screw in until it bottoms out gently. Play around with this making sure this works like the lawyers want it to. Namely, the gun shouldn’t go off when the safety is on. It should slide on easily when cocked.
Ok now we take everything apart one last time. This pic shows where you lube both sides of the trigger assembly with moly or synthetic grease. DON’T apply to the sear surfaces.
If you have access to some more serious machine equipment you can drill and tap the trigger shoe for improved pull, this is extremely hard metal and you’ll know up front what you’re in for. Drill a #29 drill and tap 8-32 blind screw, this will adjust the creep down to zero and will enable you get the pull to less than 30 ounces. The pencil point shows where to drill and tap. This pic shows the set screw already installed. You can see it in the above photo as well. As an afterthought you may be able to bring it to a machine shop and have this done, who knows?
This last pic shows the completed trigger assemble installed with the new set screw. The new homemade wire spring and sear work. And NO tension on the spring wire, again, with the wire barely resting on the back of the trigger the pull is about 18 ounces, very tempting but very dangerous. You must have adequate tension for everything to work in unison.
Enjoy, These Savage triggers can be adjusted safely down to 2 pounds with only a little bit of careful work.
