Hi Folks,
I'm
looking for definitions of two stage triggers as opposed to single
stage.
We've had a bit of a discussion on the matter in our club, with
various opinions.
Has anyone any thoughts on the subject?
Cheers, Lawrie

Lawrie,
A two
stage trigger has two definite stages, first, a "take-up" stage, and then a
"release" stage. This is usually accomplished either by the configuration of the
trigger cam, which contacts the sear, as on military rifles, or separate spring
adjustments for the two stages, as on target guns. The benefit of two stage
triggers is that you can take up the first stage, hold, and then follow through
with the shot, when the sight picture look right. The perceived weight of the
firing stage, being the difference between the two stages, is lighter than the
actual weight of pull. Ex: Your 10m Air Pistol, can have 350gm take up pull, and
a 400gm. final pull. This will feel like a 50gm. pull...Paul

Hopefully, you
adjust and weigh your trigger to 500gm or more well before an international
(ISSF) or USA (USAS or NRA) competition! Do this well in advance so that you are
used to the weight you will have to use in competition.
Your required minimum
weight may vary in other countries. "Feel Center!"

I'm looking
for definitions of two stage triggers as opposed to single stage.
A two-stage
trigger is one that has a first stage of what's called 'take-up' where there's a
little resistance but some 'play' in the trigger. Then you come to the second
stage where suddenly it gets very crisp and you can tell that by pulling just a
bit more, you'll fire the gun.
I absolutely love two-stage triggers. That's
what's in my Steyr LP10P and LG10P, my Pardini SP and even in my match AR-15.
And I just sent my old Savage-Anschutz Modell 64 off to Gunsmithing to have them
replace the old single-stage trigger in it with a modern two-stage trigger. For
my money, if you want to do precision shooting, a two-stage trigger is the only
way to go.
What's great about two-stage triggers is that it lets you get
your grip settled, including how your index finger is positioned on the trigger
without having to worry that you might fire the gun before you mean to.
With
a light single-stage trigger, I always have to be careful of as I bring my
finger onto the trigger. The problem is that, by definition, your finger is
moving as you bring it onto the trigger. With a two-stage trigger, you can
settle out all the movement in that take-up stage so that when you reach the
second stage, you can be very still and only have to move your finger just a
tiny bit to fire the gun. I find I have much more control that way.
