In the early 20th century, revolvers were the best tool suited for personal protection. Then, semi-automatic pistols came into play and changed the place of the revolver as a firearm for self defense. Now, 100 years later and the technology of speed loaders and magazines, there are fewer obvious advantages to being armed with a revolver compared to that being armed with a modern semi-automatic pistol.
While the question of whether or not revolvers are still relevant or if semi-autos better than revolvers is a popular one, we need to focus more on who is using these guns. For example, if you’re a fan of semi-autos, you might take the question and consider merely the mechanical and technological merits of the options at hand. Taken that way, of course semi-autos are superior. They recoil less. The triggers are easier to manipulate. The sights are usually much bigger and better.
However, there doesn’t have to be a winner and a loser. We can compare these two technologies without implying that the gun with the less optimal “pros and cons” list is completely useless and that everybody who carries one is ignorant.
It’s important to note that a new technology doesn’t always displace what came before it. Firearms were a big upgrade over swords and bows but they didn’t completely eliminate the usefulness of hand to hand weapons. To this day, blades are still frequently used as a last ditch self-defense tool when the firearm fails or is not accessible.
Without a doubt, modern semi-auto pistols provide many mechanical advantages over revolvers. However, that fact doesn’t at all contradict the idea that revolvers can still be viable for self-defense today, and may even excel in some areas that semi-autos do not.
