trigger stops

Here is a subject to talk about.  Trigger stops on a 22.  Good, bad?  I have mine set at the width of a piece of paper from a target, .003 to .005 thousands.  I know everyone uses one but, why?  I was thinking unless you have prefect straight back trigger release your pulling 2lbs then all of a sudden it releases and slams into your frame.  Doesn't that cause movement?
I don't have that perfect release yet should I be getting out my Allen wrench?

I used the stop on my High Standard Trophy.  And I use the HS Sport King which has no stop.  The SK is set up 10X barrel, dot, and grips.  I never have noticed a difference between the two.

Good question, and I think the answer is "maybe". I think it depends on the ratio of sear release force to the remaining return spring force at the time of release. If there is no spring, and all sear, the trigger surges, and the gun can move. Good revolvers without stops has significant rebound spring remaining so the release is good.

My airgun and 22s had no stop. It may be more important in a 1911 with a crisp trigger than a 1911 with a KC roll. 

I would love to hear Jon E. and others opinions as well

Not sure on .22's but don't use or remove most of mine unless built in. Reason is any grit or buildup could interfere with release of the hammer.

And maybe grip becomes even more important with a poor trigger & stop settling?

I was wondering if anyone else had any more thoughts on this.  It's interesting that Jack felt there was not much difference.

The trigger stop should set as short as possible or very long (or not used). You either want to hit the stop immediately after the trigger breaks, preferably before the bullet starts moving, or you don't want to hit the stop until after the bullet is gone. Tony Brong did a blog post about them saying many high masters don't use a trigger stop. I suspect the effect of hitting the stop is small, but at that level it is noticeable.

I like the feel of a trigger stop, but I don't know if it's hurting me or not.

I have a 17-4 that was tuned, (no idea by whom) and has a stop
it is set so you pull the trigger, hit the stop, and just a bit of squeeze and it fires, 
the back of the stop is rubber, so you are compressing it just a bit, 

very accurate gun

Personal I like the over travel screw. Once the trigger breaks the shoe stops. With a crisp trigger, it makes a difference for me. I am more consistent with it then not. Is there a right or wrong. No, it has to work for you.

Took my overtravel screw out and have been dryfiring my gun.  The dot seems to jump a little more than with it.  I will see what happens when I get to the range.  Tomorrow, maybe.

Over travel screw helps me from not doubling with my Hi Standards. I tend to ride the trigger too much.

I wanted to share my findings about my trigger stop.  Took it out and dryfired it for a few nights.  To me it seem my dot was moving more.  Figured I won't know for sure till I went to the range.  Well, shot today and ended up putting the stop back in.  I think my trigger had more distance to  torque without the stop.  It was worth a try.
