Has anyone used one of these? How accurate is it? Can it be used to weigh real light triggers like those found on air pistols and air rifles?

I have used one. It is reasonably accurate, but should not be relied upon for making sure your trigger weight meets ISSF rules. It is sensitive enough for AP triggers (500 gm), but not for FP triggers (<100 gm).

I agree with Fred it good for roughly measuring and setting triggers, but I too wouldn't rely on it to check if a trigger is legal.

Fred M and Richard,

When you used the Lyman gauges, were you able to get consistent (as opposed to accurate) readings from them? My gauge seems to give wildly different readings under what should be identical pressures. Do I just have a bad one?

TIA,

Thanks for your experiences with this scale. BTW, I don't see in the NRA rules where the trigger weight of the free pistol has limits.

I could get it to repeat reasonably well I'd say within 10 gram or so.

There is no free pistol trigger weight limit.

Some still like to measure them to know where they are at, if that is why you're asking.

Actually, I thought Fred might have been aluding to a minimum trigger weight for free pistol in his response. It made me look at the rulebook, not a bad thing. I thought the rule might have changed.

Misny - I was just referring to the fact that most FP triggers are set below 100 gm

FredB - my experience is similar to Richard's. +/- 10 gm is typical. You need to maintain a consistent geometry, and you need to stop as soon as the trigger releases.

It's really important to have a consistent technique when using it and stop as soon as the trigger releases.
