Well here we go again.
Yes revolvers can fail just like autoloaders.
This is NOT a revolver fail this is a ammo fail. When you have a autoloader that won't feed a certain brand or style of ammo but feeds a different brand or style of ammo it is NOT the guns fault if you try to use the ammo it doesn't like.
If your autoloader has malfunctions with one particular magazine then DON'T use that magazine anymore. It's not the guns fault it's that magazines fault.
Op found a cracked case mouth so that is certainly not the revolvers fault and maybe not even the ammo makers fault as it happens some times(I wouldn't condemn a ammo manufacture for one bad round). I always check the primers and crimp on my carry ammo for revolvers and autoloaders.
If you are getting bullet creep with a certain brand all the time DON'T use that brand of ammo in that gun.
I've said it before and here it is again. A revolver can fail but it is many times less likely to fail than a autoloader and that includes actual gun failures(parts breakage) and malfunctions either operator induced or gun induced.
Carry what you are comfortable with and know how to use it.
I guess in my mind an ammo failure that produces a total stoppage is the same thing as a firearm failure in how it affects me, the shooter, in that moment. Yes, the AMMO failed here but in doing so, by their design, this kind of ammo failure usually leads directly to you now holding a paperweight with regard to revolvers.
So from a functionality standpoint, and a “am I holding a lifesaving tool or a paperweight” standpoint, the mode of failure is irrelevant. To me, in that moment, all that matters is that the tool I brought with me is useless. Thus, while I wouldn’t call up S&W to complain, I WOULD consider the firearm an element in the failure chain.
I’m not at all saying people shouldn’t carry revolvers. Far from it! But if they’re going to do so, they should be aware that they’re not immune to being rendered useless in a defensive situation, only that their mode of being disabled is likely to be different from an autoloader. That’s all my post was getting at. In the infinitely small chance that a round jumps the crimp in an autoloader, 99/100 times I can switch mags and be back in the fight pretty quickly. Not so with a revolver. In contrast, I can limp wrist a revolver all I want and not have problems, but I’m not guaranteed that ability in an autoloader. They’re just different animals. Learn what your specific tool needs/wants, then train to that standard.
