STI Targetmaster trigger weight

[Macca]

I would be interested in hearing anyone's suggestions about slightly increasing the trigger pull weight of my STI Targetmaster.

It is a bit hit and miss in passing equipment control for competition where I need to meet a minimum pull of 1589 grams...sometimes it passes and I can lift the weight, other times it just goes....I'm wondering if I can just run with it as is and take my luck but if it gets caught have a spring to swap?

Is this easily enough achieved by a spring change? or do I have to change the whole set of springs?...I'm only looking for a minor adjustment

Just a bit more tension on the left leg (looking from the rear) of the sear spring will increase your trigger-pull enough to satisfy what you want to do here.

I would put more tension on the center leaf of the sear spring or go to a higher pound mainspring.

The best solution could be to use a new different sear spring do adapt to your specific needs...

Otherwise, you have 3 way. Two easier but not balanced... bend ahead (looking the gun as you're aiming) or the sear leaf or the disconnector leaf. The third harder to obtain but balanced is to bend ahead both but less that you bend only one.

Its basic your goal on the trigger weight. If you wanna a reset faster you shoud work on the middle leaf (disconnector leaf), if you wanna a "unhook" harder of your hammer you should work on the sear leaf...obviously bending ahead it....

I hope it helps.....

Which match has an odd ball trigger weight of 1589 grams ???

Like most people have already posted..just give the left leg on the 3 finger spring a gentle bend to put a tad more arc into the spring.... thououghly scrub the sear and hammer with brake cleaner to remove any teflon or PTFE if you have been using lubes with that stuff in them.

The trigger will be a bit more consistent with just plain old oil..... oh.. make sure the person who is testing the trigger knows how to lift the gun correctly - that can make a world of difference.

WA1500 has a minimum of 1589grams. When the gun was brand new you could get it to lift the weight once out of three attempts.....so obviously its right on 1580 something, and yes I know how to lift it correctly...spent many hrs doing equipment control for comps.

Macca,

Before you go making your trigger heavier, I suggest that you read the National Referee Council's Rules for WA1500 as adopted by Pistol Australia.... Rule 4.2.2.1 says "Minimum trigger pull of 1360g"

(Link is Straight out of the NRC Website and rules were adopted January 1st, 2008)

That means you can LIGHTEN your trigger by 200 grams - not make it heavier.... unless you need to handicap yourself.

From results posted on the various sites it seems that most Aussies are using their Service Pistol guns to shoot the match... some handy scores around the 1490 mark are even appearing...

wow...must have missed that...rules are changing all the time.....I did my last r/o reaccreditation earlier this year and it was 1589grams then.....maybe the NRC had a misprint...thanks I will get the latest copy of the rules.

some great scores are coming out of our service pistol shooters....and I have to say, I find WA1500 easier than service.....much less rushed/restricted on the timing

Service is challenging.... plenty of dry-fire training is the answer. WA1500 is like Service on valium...
