Trigger Pull... A Personal preference..

The USAF trigger, having very little after travel, tends to improve the "Trigger Break" feeling.. Part of this improvement is due to the trigger finger having light contact with the rear edge of the trigger guard..

After being taught to have no contact between the trigger finger and the stock has always left a feeing of too much finger independence.. The key to this secondary finger contact allows a more complete focus on the amount of presure required. Maybe having light trigger guard contact acts as a support closer to the job at hand..

Once an acceptable sight picture is aquired the focus can be shifted to the Breaking of the trigger, no attempt is made to focus on both.. I don't agree with a recent comment offered by a Member that there is no such thing as "take up", only 1st and 2nd stage, I have never been on the Line telling myself, OK, get on with the first stage, now the second stage.. The fact is, take up is the performance of the first stage, first stage is but a name for a performance.. Art

Art, yes the shooter does usually 'take-up' the 1st stage trigger movement.
My 'technical point' is that there isn't a portion of trigger movement that is 'non-functional take up'. The movement of the trigger during the
1st stage 'mechanically changes' the sear engagement from 'full sear engagement' to the start of the 2nd stage where the sear engagement is minimal.

It's a small point, but there isn't any 'wasted movement' (except after hammer release) with the M1/M14 trigger. The 1st stage having good sear engagement is what helps the rifle avoid accidental discharge during handling.

A long time back I remeber seeing a a M14 trigger housing that had a boss welded behind the trigger opening, drilled and tapped for a set screw. Wasn't a Rader trigger-just similar looking. Wonder if it was to limit trigger over-travel?

Jay,

I undestand your rcomments and agree.. The danger with the USAF modification is it is possible the hammer will miss the "hand off", which always comes as an unwanted surprise..

Their USAFmethod to control over travel also invites hand off problems if not done with great care and experience.. Having said that,, I prefer to keep the metlhod to myself..

Best regards,, Art

Similiar, he put a spot of braze on the back of the trigger, filed it off until the trigger broke at the very end of travel.. The same danger of a missed hand off exisited... Art

The purpose of reducing over travel is achieving less disturbance to the rifle once the hammer is released. Seems like a small thing, but almost all match triggers in hand guns and match rifles, other than service rifles, have over travel adjustments. Art makes a good point in that the trigger in Garands and M14's can end up doubling when the OT adjustment results in insufficient disconnector engagement. I have seen M14 trigger groups that have been modified to reduce OT. When it works it's a good thing, but one should be very careful with service rifle triggers.

Thanks from M14vrp and mic52

Often times I wished I had a two stage trigger for my Palma Rifle for normally those triggers are set quite light and little if any travel prior to firing. That is both an asset and a minus for if your sight picture using micrometer rear/globe front set up at 8,9, and 1000yds. happens to go dim on you, breeze kicks up, eye fatigue, etc. you do not have a second chance to correct or hold up if you are not very, very, careful and result is not an X or a 10, but a 7 or 8, not good. I personally find the M14 at required 4.5lbs. with the take up prior to actual firing is quite manageable with practice and regardless of how much effort has been put into the rifle with some magic barrel, stock, bedding, "holy water blessing," it all comes down to trigger control and sight picture. This is especially true firing unsupported, sling positions, as in High Power or Long Range/Palma matches. Even from the bench with some super duper optics, often times the errant shot is not due to load, rifle, scope, wind, but poor trigger control by the shooter and can cause shots way off where you wanted it to go. Just my experience.
