I would believe today's pistols with good ammo are MORE reliable then revolvers under real world and rough testing.
I have to disagree with this. While today's semi-autos are a vast improvement over those of the 60's and 70's as far as reliability they still are not nearly as reliable as a revolver. It is a simple matter of the complexity of the two guns. There are just too many more things that can and sometimes do go wrong with or break in a semi-auto compared to the revolver.
Safeties and magazines add undue complexity that you do not have on a revolver, not to mention the frame sliding back and forth and all of it having to happen in perfect harmony to function. Anyone knows that anything mechanical can fail, and the more complex something is the greater the potential for such mechanical failures. Even if I had not been shooting both for well over four decades and still shoot a lot, the mere fact of the complexity of the two types of weapons makes it almost impossible for semi-auto’s as a group to be anywhere close to as reliable as revolvers as a group.
While revolvers do jam or break, it is much rarer than having a semi-auto jam or break. In fact in all my years I have only had one misfire of a revolver and that was a M617 rim fire .22 LR that did not fire the first time, but did the second time it was struck by the firing pin. I cannot count the number of jams, failure to feeds, and broken parts I have had on semi-autos. It is many, many dozens of them. The worst was about three years ago with a Like New Colt Combat Commander 1911. It was the worst gun I have ever owned and so unreliable it was never carried or shot away from the farm. It is certainly not the only semi I have owned with a variety of problems.
Certainly the change of police forces from revolvers to semi-autos has led to a much more wide spread acceptance and usage of semi-autos and to an improvement in their reliably. The handguns seen in movies today and on television are for the most part semi-autos. Semi-Autos are flatter and can be easier to conceal than some revolvers. The primary advantage of semi-autos is their fire power for the average shooter and ease of reloading with a magazine.
Of course for an expert like Jerry Miculek a revolver is actually faster and can deliver greater firepower than a semi-auto, but not many people have Jerry Miculek’s skills nor do they have the time and patience to practice like I expect he does to have such proficiency with a revolver. (He shoots a S&W 625 using moon clips by the way)
Until the last year I carried mostly third generation semi-autos and I still have a great many of them as I consider them to be some of the finest semi-autos ever made as far as reliability and over all quality. But I now carry concealed a revolver, mostly a Model 696, with a 649-2 in my pocket sometimes. I made this change due to the simplicity and reliably of a revolver compared to a semi-auto.
The chances of me needing more than five or ten rounds in this area is slim to non-existent. However, if I do need a weapon, I want it to work and that means the most reliable gun I can possibly carry and for me right now that is a M696, or sometimes a Ruger Speed Six, and on occasions even a M649-2 BUG.
