Well my 686 has about 90% strike rate on geco factory loads. The trigger job is quite nice so I don't want to buy a spring kit so how do I adjust it abit to get better strike rate.

If it helps I do have a brownells and Wilsons Spring kit. P

Install a new strain screw. If it still hits light, shim the end of the screw. If that's too much hassle, take the mainspring out and bend it a little "flatter".

I opened her up and installed a new main Spring. The trigger is deffinitly got more force behind it and the single action is just as crisp.

Least now I can wind it out till I find its sweet spot. But least I'm happy now and learnt/gained confidence on working on my own firearm.

Unfortunately in Australia we can't go try the handgun out we can only use our gun at the range which is a open outdoors range under the instruction of a range master. They have no tune/practice days so it means I'll have to try it at the next competion.

That's the problem, the strain screw needs to be fully tightened.

It is not for adjustment.

As bigbruce stated, that screw is not meant to be adjusted out. Tighten it all the way, shoot, enjoy.

Sometimes they get cut off so they can be screwed all the way down and still load the spring less.
Hence the recommendation for a new one.
A primer cup will shim it well enough to get by. I have one such that I put in and found another "installed" by a gunsmith when I changed grips.

I have a new one that measures .4205"

I am really confused---I have heard for years "screw is NOT for adjustment" etc. and it makes sense to me. , but then every now and then you run across a Jerry Miculek video shown working on the many revolvers that he maintains, and every time he spits it right out there about how he tweeks the revolver by "turning THAT screw" to his liking. and we all know how good Jerry is......

True,but that's all Jerry does day in and day out year after year and he ain't being attacked by bears

Technically it is not for adjustment, but when you shoot more in a day than most guys shoot all year like Jerry, then making minor tweaks on a competition only gun where you can test it on the fly, and adjust it numerous times to fit your primers and shooting style in a single session, then messing with that screw is a non-issue.

For us regular joes who might hit the range one or three times a month not so much.

Like the legend Jerry M says. Leave the grips off. Back off the screw till it fails to fire then screw it in till it fires every time. Install grips and enjoy your new lighter DA trigger. That screw doesn't need to be screwed in all the way. Will it be more reliable will all brands of primers screwed in all the way? Yes. Does it matter with a range gun? NO.

My gun is a range only gun it's highly illegal to use it for self defence or carry here in Australia.

It is screwed in the whole way was going to back it off till it failed to strike primers.

Screw looked to be full length.

There is an old timers temporary solution to your issue. This is only a temporary fix. Back out the strain screw, put a used primer between the screw and the spring anvil side to the screw, and screw it down tight. This should hold you until a new spring arrives.

I hear what yer sayin, BUT if he was, I would sure feel sorry for the Bears.....lol

I do the same thing but I use blue Loctite to keep the screw from walking out. The official command is that the screw must be tight.

On your 686 I would remember that all ammo makers use different primers on their cartridges and some are hard and some are soft... I would try different brands of ammo, which might be difficult for you to do since you can only shoot in matches. Geco may use a hard primer. You said that you have a "good trigger" but springs also get old and may need replacement.
