Most of the firearms were made with safety to the shooter in mind, got to give them credit!

A friend tried to shoot a 308 cartridge in a 20-06 it chambered OK but when he pulled the trigger it blew the shells in the magazine to the ground, the trigger went somewhere and I have the bolt with the cartridge stuck tightly to
the face of the cylinder..

It was a Remington 700, he was not injured just scared. I do not ever stand on the right side of a right handed shooter just for this reason.

Smith & Wesson has been very safety conscious for a long time, I do not own any of the new plastic stuff so cannot speak for them.
