It's certainly possible that the OP accidentally pulled the trigger in a subconscious effort to catch it.

It's also possible the trigger snagged on some clothing as it dropped.

Finally, it's ALSO possible that his weapon was not in proper working order... these are mechanical devices, and require proper maintenance and care.

Without being able to closely examine the weapon, all of our input is simply conjecture, as the first 2 possibilities require witnessing the event.

If the weapon did indeed fail in some way, it would be to our benefit as a community to know the particulars. So let's not just jump to conclusions as to what did or didn't happen yet.
