I don't on 110 either, anything above that, gets turned off and tested off before being worked on.
Still a ND...your fault or not. In the case you implied, it's a manufacture defect, thus a manufacture ND. If you owned the gun for a while and it goes off, it's your ND for not regularly inspecting and making repairs prior to loading the gun.
INGO IS FULL OF RETARDS!
When I was a kid my 2nd cousin (my uncles age) was drunk one night and shot a hole clean through his roof with a 12ga. He immediately walked to my uncles house and gave him the gun and told him to hold it a few days lol. They shot and hunted together a lot back then. You could stand in the living room and see sky.

As someone with deep Scots Irish Kentucky roots (Muhlenberg, Ohio, Grayson County area)why did I know your location would be Kentucky???
It's genetically in our DNA after getting likkered up to fire a minimum of one shotgun blast into the air...I think it's in Kentucky's Constitution as well as our genetic make up...It's kind of embarrassing really but it's there....If your 2nd cousin (another Kentucky thing...Actually knowing your 2nd and 3rd cousins) had shot outside the incident would have never even raised an eyebrow.....
Sounds like the leaf spring was loaded a little light against the sear.
That'll happen with a 1911 real easy when trying to drop the trigger pull weight with a new or tweaked leaf spring without using a lightened trigger.
Need to be careful with that because that condition can cause one to start doubling or go full auto out of the blue.
Yes it can......ask me how I know.
How do ya know?
I clean my loaded gun all the time! Unloading it is so passe'.
Just once I want to hear, "yeah, I had an ND, but the bullet ended up one foot into the sand and not my waterbed/ceiling/wall/dining room table/neighbor".
When you handle guns a lot. Unfortunately, the sad truth regarding ND/AD is; it's really a matter of when you have a ND/AD, not if you'll have a ND/AD.
The bottom line is to keep the muzzle pointed in a safe direction, and never at something that you don't intend to destroy. So when it does occur, no one get injured.
The above statement isn't meant as a lecture, just a few words of friendly advice.
