So, just reviewing 2019 Handbook Rules and thought I would stimulate some discussion with this post. Interested in interpretations and thoughts on this ruling exception and how it relates to the ruling of DQable offenses:

10.4.3 A shot which occurs while actually loading, reloading or unloading a firearm. This includes any shot fired
during the procedures outlined in Rules 8.3.1 and 8.3.7 (also see Rule 10.5.9).
IPSC Handgun Rules, January 2019 Edition 34

10.4.3.1 Exception – a detonation, which occurs while unloading a firearm, is not considered a shot or
discharge subject to a disqualification. However, Rule 5.1.6 may apply

A detonation is not a shot. It usually occurs on unload show clear and is when the primer hits the ejector (which by the way os why we discourage people from covering the ejector port while unloading .) For some reason 40s seem the most prone to this.

Interesting. Does this condition (primer detonates but powder does not ignite) exist often enough (ever) to warrant its inclusion in the rules? Seems more fit for a flintlock muzzle-loader with wet powder in the pan...

Please enlighten me.

Thanks much.

There was a video online of the guy unloading a 2011 with no finger on the trigger or hammer follow, recorder in the third and first-person views, he did the old flip and catch, primer hit something on the gun and went off.

If I find the video, I will post it. the video was from the US I think a 3-gun match, the guy got DQed and argued it.

Apparently, this is a thing with 1911/2011 guns, specifically a .40

Thanks for sharing Dima, Interesting.

Again, though, did the firearm discharge and a bullet flew out of the end of the gun or did just the primer ignite? That seems to be the weird one-in-a-GaZillion occurrence.

Again, this is not a squib discussion which is covered in another section.

Cursory call would be DQ since the gun discharged during the UASC procedure, which is the "Unloading" part of that...

I have seen it happen twice both were 2011s in 40. In both cases the carriage detonate outside of the chamber. in one case the RO caught a piece of brass in his arm.

When they brought this rule in it was said it was because of those of us who were doing a flip and a catch. However in both cases I saw they were trying to tilt the gun and have the loaded round fall into their hands.

Does it happen often? well I have been shooting IPSC since 1993 (there was no such thing as a 40 then) and like I said I have seen it twice. The reason for the rule is it is not a shot! There is no bullet leaving the barrel .

Wow. Now I understand the scenario better. So, rare, but possible.

Thank you for that Walter.

But to clarify, the detonation does not mean that only the primer ignites. The powder does too....
I think Timmy had this happen to him....................

It's a reason I don't catch or cover the ejection port.
