    Sigma first failure

    Went to the range to day and after about 50 rnds the sigma would fail to cock the firing pin allthe way.but enough that taking the gun apart wasnt posable since it has to be de cocked to remove the slide and the only way to d cock it is to point it in a safe derection and pull the triger. after making sure its not loaded and dosnt have a mag in.
    i couldnt get it to dry fire and finaly chamberd a round pointed it down range and got it to fire. then dry fired it and took it apart. give it a quick cleaning and lubed it. now in the book sent with the sigma pointsd out the oiling points and dosnt say to oil the firing pin spring but it fired flawless ly after i did wounder if i have a week sping or some thing. all other guns i took each ate a hundred rounds np.
    obtw thought id post this because i have to say the sigma has eaten any kind of amo this was winchester white box bulk ammo from walmart 16 dollars a hundred 165 grain

    Were you trying to dry fire it without a mag in it? I think those have a mag safety on them. My bersa is like that and it freaked me out when I tried to dry fire it until I realized what the problem was.

    Freedz no mad disconnect in Sigma's

    Snake have you been oiling the connector thats hooked to the trigger?

    check it and clean it that is what cocks the firing pin to fire if it gets gritty it can not fully cycle
