I was helping a friend re-mount a scope on his Sako 270 and he asked about lightening trigger pull. Anybody have directions or a source? Should this be left to a gunsmith? Bob

Bob,it should be the front bottom screw,which is held by a metric nut,loosen the nut,back out the screw a bit and keep adjusting till you get it lower,tighten the nut .Make sure it will cock and not slam fire on you when closing the bolt briskly,all with the rifle unloaded of course.I have never had one that needed to have sear,or overtravel adjusted,and most will go down to about 2# safely,but be sure the safety will still work as you go lighter.Sometime the safety won't work if you go too light!!

WTB gives a good description.

You can almost always lighten them to the point that they will slam fire if the bolt is worked briskly. There's no cure for this that I have found other than turning the screw back in(clockwise, increasing weight of pull) until the most abusive working of the bolt does not result in the sear disengaging.

The other two screws do not enter into the weight of pull. The one on the upper frame of the trigger simply snugs the trigger to the frame of the receiver. The other little screw adjusts overtravel and rarely needs to be adjusted. (Hint, adjusting all of the overtravel out of the trigger will increase the weight at which it slam fires, so don't get too aggressive with this adjustment. Some overtravel is necessary and is not detrimental to trigger feel or function.)

Once you have the trigger the way you want it, it is not a bad idea to place a dab of clear nail polish on the locking nut to assure that it stays in place. Actually, I don't do this to mine, and have never had one move.

The sear engagement can be adjusted with most, but not all, Sako triggers with a screw found in the top of the trigger frame which can only be accessed by dismounting the trigger. As WTB says, this usually is not necessary or advisable. Some of the older triggers do not have this screw sear engagement adjustment, rather just a fixed "bump" which bears against the receiver frame.

I've run across a few Sakos on which the triggers simply wouldn't adjust as low as I would like. I'm sure that a professional could remedy this. However, most Sako triggers will adjust to a very crisp weight that is uncomfortably light for people who are used to "typical" sporter rifles.

thanks!! bob
