I had a Timney trigger put on my Ruger model 77 years ago and it wasn't right after that. I closed the bolt with the gun pointed to the ground and blew a big hole in the ground. Another time I shot a deer, tried to shoot another and couldn't get the button to stay back as I closed the bolt. Finally it stayed back but went off when I took the safety off. I had that gun looked at by 4 gunsmiths but none could fix it. Finally sold it to a gun shop with the original trigger and told them what was wrong with it. I hope to heck they fixed it for good before reselling it.
I knew before but the point was driven home with that gun to always keep the safety on, finger away from the trigger and the gun pointed in a safe direction.
