A lot of the history of firearms development is about increasing the speed that a firearm can be fired and the number of rounds it can hold. That's why most police army and civilians use high cap handguns. If some think 5 is enough then they are going against the thinking of the firearms industry for the last few hundred years.
PS That's why the revolver is going down the same route as the Dodo.
I'm a pretty hardcore semiauto guy, but I can't agree with that statement.
Overall, I'm disappointed that revolvers don't seem to be evolving as much. Then again, the design has been around so long it may be tough to do more than incremental improvements, and we are seeing polymer designs so maybe progress does march on.
That said, revolvers have their place. A gun is better then no gun and it would be foolish to overlook the difference in caliber selection between revolvers and semiautomatics. It is very difficult to get something with the power of a .357 magnum in the size of a snubbie for a semiauto carrier.
In short, I won't criticize someone's firearm choices so long as they have a weapon they believe will perform when they really need it. To me, reliability trumps all other factors. If you pull the trigger and nothing happens, it won't matter how big the bullets are, how accurate the weapon is, or what your capacity is.
If 5 shots in a cylinder buys you peace of mind, so bet it. I know from my readings here and looking at different data since I re-entered firearms ownership I am now challenging a lot of my assumptions.
I was only half-kidding with my initial post though. I've known a few people who have been in gunfights, mostly police officers but not all. No one ever complained they had too many bullets on them.
