I own both an auto and a revolver, but I am much more comfortable carrying the revolver. I have a Ruger SP 101 2.25”, which has a trigger pull out of the box in excess of 11 lb. The trigger pull and the transfer-bar safety make accidental discharge nearly impossible.
I would never carry a Glock, which only has a trigger safety that could prove worthless if the trigger snags on a bra or in a purse. My Springfield XD subcompact has both a trigger safety and backstrap safety, and while I deem it more safe than a Glock, I don’t think it is as safe as the revolver.
I actually think my XDM is safer than a revolver, particularly as it would be quite difficult for a child or someone that did not know how to handle a firearm to accidentally discharge it. Your hand must be big enough to fit around the backstrap and reach the trigger. An accidental trigger pull alone will not allow it to fire no matter what.
Having said that I never rely on any sort of safety mechanism other than the brain and unwavering vigilance.
