    Sa/da=da/sa?

    OK, explain SA/DA to me. I've only owned SA 1911's. I know what DA/SA is...first shot is DA then each successive shot cocks the mechanism. Is SA/DA just another way of saying the same thing or is it different from DA/SA? Thanks.

    SA/single trigger action. DA/ double action trigger. DAO/ double action trigger only. SA/DA trigger can be used either way.

    SA/DA COULD be different - some guns (I think the Taurus 24/7) have a SA pull. But if the gun has a hangfire, the 2nd pull is heavier - like a DA pull.

    Yep the Taurus 24/7 is at little different, it's SA with second strike capability, so it's not SAO, it reverts to DA if their is a failure to fire, you can't start it off in DA though...pretty good concept, I've had a couple of failures to fire in my PT-145 but all fired on the very next trigger pull....A DA/SA gun would give you second strike capability too, but in the 24/7 you get the best of both worlds, always has an SA trigger pull, but just squeeze the trigger again if there's no bang, no clearing drill needed unless the second or third strike doesn't do it.

    I prefer the newer term TDA ("Traditional Double Action") when referring to autos that start as DAs then revert to SA after the first shot.

    Actually, I call them Crunchentickers in conversation, but that seems to offend some people.
