I own several 9mm Glocks and I own several no-lock S&W J-frame revolvers.

I consider the Glocks to be more DURABLE and tolerant of ABUSE, whereas I consider the revolvers to be more RELIABLE and tolerate of NEGLECT.

Out of the box, I have a great deal more confidence a revolver will reliably go bang over any auto. If both are in good condition and well maintained, I trust the revolvers to function reliably in any defense situation(shooting from awkward positions, with a one-handed and less than ideal grip on the weapon, in contact with assailant(s) or own body or clothing, with any ammo) over any auto.

A Glock will definitely stand-up to the abuse of shooting hundreds of rounds(without cleaning) better than one of my J-frames or a military environment, but so what. That is irrelevant to me as a civilian who doesn't abuse my carry guns. I even have a designated snub that I do most of my training and practice with and think that's a good idea regardless of the type of weapon.
