Explaining the Sig "4-point safety system".

[nikon777]

Sigarms unique 4-Point Safety System goes far beyond what you'll find on other pistols. Their safety system consists of (1) a patented automatic firing pin block, (2) a decocking lever, (3) a safety intercept notch and (4) a trigger bar disconnector. (sigpro line)

1. Ok, I get the function of #1, 2, and 3, but how exactly does the trigger bar disconnector work?


2. Also, on the newer Sigs, is it still possible to bypass the hammer intercept notch by thumb de-cocking(i know, a big no no. I use the de-cocker). I seem to remember a story of a LEO who thumb de-cocked a Sig, he dropped it on the hammer, and fatally shot himself. Don't recall the model, or when it happened, I do believe it was an older model though.

When you puul the trigger it moves without engaging the hammer, the bar unlocks and lets the trigger move 'freely'. Been around for a while on other guns. I have a M95 Browning clone that has one, keeps you from breaking something when the pistol is on 'safe', also make for a sweet feeling trigger pull. At least thats my understanding of its use...
