What do you use for checking 500gr triggers?

500g trigger weight?

Why didn't you just say air pistol weight?

Anyway, you bend a coat hanger, tape two tins of pellets to it, and if you can lift the gun with the "weight" hanging from the trigger it is heavier than 500g.

This has been covered multiple times here. Try a "Search".

Rover, I've been trying to do as you suggest for the past hour. Now, there are little bits of white plastic coat hangers everywhere and my wife is pissed. What next???

Use a metal coat hangar, or simply tape the two tins of pellets together and then tape a string to them *about 18'). Tie the string to the trigger with a simple loop, cock the rifle then lift the rifle until the weight is lifted. If it firs it is too light.

Pat, it seems the OP is taking about pistol triggers (after all, there is no rule that I know of that states 500 g. weight limit in rifles, and he created his thread in the pistol forum) and in that case, the string loop`is of no use.

In most rifles it wouldn't be useful anyway, as it implies removing the action from the stock, and the rules are that the gun must be checked in full dressing, that is, as they will be used in the match.

The wire metal hanger seems to be the most practical aproach for those who will not bother to build themselves al proper weight, which isn't at all complicated.

You can always fork out $500 or more and bought one from ISSF....a clothes hanger and a jar of casing is cheaper.

As well as a trigger weight you can use a Analogue gram dial gauge,1000-200-1000g
Helps set up first and second stages.

I know this from my rifle shooting. The trigger has to lift real weight suspended from a stiff rod. Strings, flexible wire coat hangers, spring type scales are not going to be accurate, but maybe it will work for 500gr. I thought someone made check weight specific for air pistol, didn't want to spend $$$ for a complete weight set.

Where did you get the idea that:-

a) The ISSF sell them.

b) They cost $500. I'm sure that there will be many sellers in North America but just look at this ebay item to get an idea of the price.

I guess things changed pretty quick within a year. I have not check the ISSF shop for awhile.

I guess Gehmann comes up with stuff pretty quickly, but I wonder if the suspension arm is a blade. They used to be round.
It looks like ISSF has withdrew the weight gauge from their shop, I cannot even find the shoebox for sale anymore, instead they come up with a cheap "Jury test set". The 1200 Euro shoe test instrument is still ridiculous expensive.

The NZ set of testing equipment, perhaps for inspiration.

Density of O1 Steel is 7.81 g/cm³. T6 Aluminum (6061) has a density of 2.7 g/cm³.

Good luck.

I can't remember ever seeing trigger weights for sale on the ISSF shop. I would doubt that they would ever have sold any trigger weights at $500.

I'm not sure what you mean by "Gehmann comes up with stuff pretty quickly"; they've been making trigger weights (in various weights and lengths) and pistol control boxes for many years.

The Gehmann trigger weight has had the knife edge for as long as it has been a requirement, and that's at least 14 years.

I believe you have mis-understood the purpose of the "Jury test set". It is not for testing pistols: it's for testing the equipment used at equipment control (and arm angles during matches)

I was just kidding about plastic hangers, by the way...

No, you weren't. You just found they were ineffective compared to the wire when your wife went into "Mommy Dearest" mode.

Hey, if the weight of a Morini CM 162EI is 1020g, then why not just
hang it upside down to check the trigger weight.
That way you don't need to waste wire coat hangers and anger the
good lady.

But that way you end up with a trigger pull twice as heavy as it needs to be!
For air pistol it's 500g, for .22 and up, 1000g.

Perhaps, if you learned to twirl it like a cowboy at just the right speed? If it does not go off during the twirl, it is within specs. If it goes off...probably a bad idea to load it first. There would have to be some kind of testing and certification of official pistol twirlers.

Aaaah this again. Here: 10$ for a 500g calibration weight - attach a coat hanger to it or wtv. http://www.ebay.com/itm/10g-100g-200g-5 ... 4d27f2ac34
