Pistol is decocked, falls on ground, lands on hammer, does it fire?

or is there some sort of passive firing pin block until you pull the trigger? namely, the sig p229.

If it is a Ruger LCP or SR9, yes.

Generally there is another safety mechanism in the gun though. This may or may not stop the firing pin from moving into the primer through inertia. Id say most guns will be fine though. Unless it is the ones in the above post.

Full-size Rugers have a decocker mechanism that prevents the hammer from contacting the firing pin if the safety is engaged. However, with the safety off, there is always the risk of any gun firing if dropped.

On a SIG of this type, when the hammer is lowered using the decocker it does NOT rest on the firing pin, but in what they call an "intercept notch" a fraction of an inch away from it. It also has a firing pin block in the slide which is only deactivated by pulling the trigger. Bottom line: it will not discharge unless you pull the trigger, period.

Not only that, but most pistols have a firing pin block. It does just that....it prevents the firing pin from moving in the firing pin channel and striking the primer. When you pull the trigger, there is a a protrusion on the trigger bar which disengages the firing pin block at the same time as it releases the hammer for ignition. The firing pin block cannot be disengaged unless the trigger is pulled. Pistols like the Sig, Glock, H&K, CZ, and many other modern auto pistol designs have a firing pin block. It is the standard now. However, there are quite a few older designs like most 1911s that do not have a firing pin block.
