Trigger pull question

Comments

    I have an acquaintance that's looking at a pitol for SD.
    He's more of a revolver guy and wishes to go to the pistol.

    He's mostly undecided on caliber, .380 to 45acp,even .357sig, but leaning hard to the.40SW.

    Anyway, this one pistol he's looking at is said to have a 16oz trigger pull in double action.
    I am leary of this,myself.

    So, the question, What is a reasonable trigger pull weight for a DA pistol?

    I suppose it's possible, but I find a 16 oz. d.a. pull hard to believe.
    A one pound single action pull would be too light, especially for SD.

    Hello I shoot a number of semi auto TARGET pistols most all of them are single action . There are rules on trigger pull weight because the matches are with safety firstmost . Even a 22 caliber has to be 1&1/2 pounds and center fire pistols have to be 3 pounds in single action mode .Double action pistols have two designs DAO is double action every time and most pistols run around 6 pounds in this mode then the pistols that are double action for first shot and single action for any follow up shots are 8 pounds or MORE for first shot and the next single action are 4 pounds or more. even targe rifles normallt have MORE then 16 OZ trigger pull

    A 16 oz. trigger pull in DA is really unlikely, if it's a DA/SA I can't imagine what the SA weight would be. If he wants a good DA trigger pull he should look at the Para Ordanance LDA series

    A 16 OUNCE double action trigger pull is not even possible on any current model gun I know of.
    But a 16 POUND double action is fairly common on some of the less expensive stuff; especially the East Bloc military and police surplus.

    Thank you, everyone for the info and reassuring my thoughts on the issue.
    I understand everyone's concern here and I did figure something, somewhere was wrong.

    I did advise him, before I asked here, that that trigger pull didn't sound right and that they should be of at least 3#s or more and shouldn't invest in that gun yet.
    But that's why I asked.

    He may just have a head full of info and may be confusing things on himself.

    I can email him or see him next Wed. when he delivers the next load.

    What they said.

    I've never heard of any double action gun (revolver or auto) that has a true double-action (ie pulling the trigger fully cocks the hammer or striker) trigger pull as light as 16 ounces, and I can say for damn sure that there is no such gun commercially available.

    In THEORY, it should be possible to create a conventional mechanical double-action trigger that could go off with only 1 lb of pressure BUT fundamental mechanics being what they are, such a trigger would require an incredibly long pull of several inches before it could build up enough spring tension to set off a conventional primer. In practice, no design like that would be feasible for ordinary use.

    In any case, a trigger that light wouldn't be safe for combat or field use. Common sense also indicates that a pull that light would offer little to no safety advantage over a conventional single action trigger. So why bother with double action at all? Some target shooters do like 1lb (or less) triggers but they all use either electronic or conventional single action designs not double-action ones. Apart from certain specific disciplines (ie free match pistol) virtually ALL of the pistol shooting sports explicitly ban triggers that light for safety reasons.

    The lightest double action guns have true trigger pulls around 6 pounds, and that's including the latest generation of nice-pull guns like the SIG DAK, and the Para LDA ("light double action"). With double action the pulls feel lighter than their nominal weight, by the way.
