Trigger Pull Variance

[Steve Menegon]

What range of pull values, high to low, constitutes what would be considered a quality consistent trigger? I've searched and could not find any numerial range that would be considered poor, average, or good. Keeping in mind +/-  of gauge operating calibration.

For example, the attached picture is my SP01 in S/A showing high and low of 10 pulls.

I don't know if I can feel a 4oz difference. In fact I can't recall ever saying "that pull felt lighter than the last".

What do you guys know or think? I'm sure trigger feels more consistent which should equate to a better shooting experience.

Fire away!

4 oz. might seem like a lot, but I seriously doubt if you (or me) could feel it. I see variances like that in my CZs, Tanfos, Berettas, etc. There's a fair amount of parts to move inside every time the trigger is pulled, and even finger/gauge placement can affect it. The only handguns of mine that show virtually zero variances are my well loved S&W wheelguns.

This is a rather interesting question as I have always been skeptical of hand held manually operated trigger pull gauges. I wonder what the true variation of a trigger would be if it were measured by a machine that always contacted the trigger in precisely the same spot with exact same rearward force applied each time thus removing the human factor. Think ransom rest for testing true accuracy VS a gun held by human hands. Just something to consider I guess.

I did my best to be as precise as I could with placement on trigger, keep the gun solid, and pull the same each time. Yes, the human element will impact numbers.

I found a calibration sheet for the gauge and it is dead on at 3, 6, & 9lb respectively. There was no +/- listed.

I'll check a few others and report on them.

I use that same gauge and never get the same reading twice. It's very difficult to hold/pull consistently. I just focus on a 10 pull average to compare before/after I make changes. Feel is more important than a low pull weight anyway.

[Steve Menegon]

I agree Earl. I got some whacky readings when I first got the gauge. I learned the gun must be very steady, keep everything perpendicular and parallel before I got consistent readings. Also be sure the little screw holding the pad in the arm is tight.

Agreed on feel vs light. Smooth, clean, and crisp.
