While a revolver can indeed have a popped primer, it’s exceedingly rare. It’s an order of magnitude more rare than a stoppage on a semi auto. Semi autos are normally far more sensitive to ammo choice. Semi autos can even jam in some cases by a poor firing grip.
And MANY semi autos can and do discharge when dropped. SO thats a moot point.
Anyone who shoots both much will experience many more stoppages with a semi auto than with a revolver. Thats just a fact. Admittedly, the semi auto will get off that first shot, but then the variables kick in.
The bottom line is that while of course not an absolute, “six for sure” is certainly approaching the accurate end of the truth meter. And revolvers for all their limitations, are far more dependable than semis. However, the difference is not enough to prevent anyone from choosing what they want and learning their system.
