Well, I’ve had my S&W 586 bind up the cylinder, had an old M&P with timing issues and an old Taurus 85CH that had timing issues that it might not reliably ignite the round and when it did, there was a good chance it would spit lead back at you. Conversely, I’ve never had a stoppage (yet) of any kind from my quality autos like HK, Glock, Sig, Walther, etc. Does this mean I wrote off revolvers? Nope. I still carry a 642 as a backup gun. However, one thing I did learn, especially with a bound up cylinder, is that when a cylinder binds up, she’s done and out of the game until you get it open which in my case involved tapping it open with a mallet. However, when an auto stops working, a “tap-rack-bang” (aka immediate action) cures probably 90% of the problems, 5% can be cured by the “rip-rack-reload-bang” solution (aka remedial action) and the other 5% is due to a broken part and it’s out of the fight until you get it repaired. At the end of the day, no matter if it’s a revolver or auto, anything mechanical can fail at any given time. So, the idea of “having 2 is 1 and having 1 is diddle” which is why I always have a backup on me as well.
