1911 trigger pull

Post by Jwhelan939 on 8/16/2013, 12:31 pm

I know the rules state that the trigger pull has to be no less than 3.5 lbs (56oz). Is that a firm line? My trigger, on an official scale is 55.35 ounces. Would they fail that? I have been playing with the sear Spring to get it just right. This seems to be the closest I'm getting without going over. I'm new to bullseye. I originally had the trigger job set at 2.5lb, which is my preference. Oh well. Rules are rules. Any help would be much cheaper appreciated. Thanks!

You definitely want it to be over rather than under.   Try setting it so it picks up about 3 and three quarters pounds, then you know for sure it will pass on the line.

It's just me...but 1/4 lb either way will never get picked up by my finger.
Inconsistent or just plain crappy is another story.
If it's a touch over & clean I wouldn't sweat it:shoot:

For NRA registered matches, a set of weights, rather than a pull gauge is used. 3.5 lbs of weight is suspended from the trigger. If the hammer does not release, a piece of colored tape is applied to the trigger guard. Generally, the weighing of triggers is done independently, by an NRA qualified person, seperate from those that run the match and work the line. At registered matches I have not seen a gun that disqualifed on trigger pull which tells me BE shooters are serious about the rule.

This topic was brought up many years ago and several list members decided to weigh the weights of their official NRA trigger weight set. A few reported that surprisingly the weights were not exact. One can then imagine that if the trigger pull is "exactly" 3.5lbs., it may pass using one set of official weights and fail with another set. So, adjust your trigger pull with a little margin of safety. Also, some have mentioned that their sear spring have lost tension with time so check the trigger pull weight regularly. I've seen a gunsmith with a 1/8 lb plate with his set although I have not seen this available.

I heard Bill Blankenship once say that his triggers are all set to 1/4 pound over the minimum allowed. He said that way he never had to worry about making weight and it kept his trigger finger used to the additional weight. I have a weight set and keep mine adjusted the same way. No surprises and I'm used to the additional weight.

Every time I've seen a borderline trigger weighed the ref or judge has tried very hard to pass the gun. Just the same, if I was on the line and didn't know my gun was well above the limit, the stress would hurt my scores far more than the trigger would help.

I've noticed that when adjusting the sear spring to obtain the desired trigger pull weight, the final measured weight tends to be heavier when the pistol was fully reassembled than when it was partially reassembled for ease of readjusting the sear.

I would like to hear from the experienced especially our gunsmiths if my observation is not erroneous.

Thank you

I always replace my sear springs each season and have the AMU at Perry check and set the weight that way I knew my trigger pull was always right.

This summer at a match Brian Zins told me that he keeps his triggers a little over the limit because he does not want there to be any chance of it failing if he were to set a National record.  

No one would want a good day ruined over something like trigger weight, national record or not.

In Zins and any other winners of big events, many times guns are checked after the match, if it doesnt pass, you are DQ, so its best to be legal, this could apply if you are moving up in class and a RO decides to check you. rule is 3.5, nothing less passes period. Also after bending the spring and shooting you will get spring set and it tends to be less than right after bending and testing, a spring that picks up 3.75 many times will not after shooting but will still lift 3.5 with no problem.
