Quick SIG decocker question

[smokehouse4444]

A friend looking into buying his first handgun asked me this question, and I just wanted to clarify with the knowledgeable peeps on this site. If a round is chambered in a SIG, HK, or whatever DA/SA and decocked, if one was to start to manually cock the hammer back for SA but it slipped before it locked and fell back down, would it fire?

No.


If you watch the video below around the 3:40 mark I explain why it won't happen (probably easier to show rather than try and describe...).

No. The firing pin block would prevent it as long as the trigger wasn't pulled.

That's what I thought, and said, but then I started to second-guess myself. Thanks so much.
