There is a minute difference in rate of fire between a revolver and a semi-auto pistol, especially in the hands of someone who fires on a regular basis. The major difference is capacity. 5-6 rounds for a revolver vs 5-15 rounds for a semi-auto pistol (depending on size and caliber). My daily carry is a .45 and depending on the magazine I have loaded, have anywhere from 5-7 rounds. Not much of a difference from a revolver. The difference here is the ability to reload quickly, which can mean life or death in a situation if I need to draw my weapon. In a situation where a "citizen" needs to fire, they are most likely not going to have any training to fall back on to ensure what they're tossing down range is effective and lethal. So now you have someone who just fired 5 wild shots, maybe one wounded the perpetrator, and since they have a revolver, is going to take forever to reload. In other words, they're most likely going to end up dead with the bad guy winning. Nope. I'm going to toss enough lethal lead downrange to ensure the fucktard stays thoroughly and permanently dead. If that means emptying 7 and slapping the spare magazine in for another 5, so be it. Because I'm not going to pussy foot around. If you want to use a revolver, more power to ya. But I'm going to ensure I can toss a lot of lead downrange quickly and efficiently.
