Why shoot a revolver when a modern semi-automatic carries more rounds, reloads faster, is flatter and slimmer, and is no more costly? Revolvers are no-problem guns. Because it has a relatively straightforward design, a revolver is very reliable. A semiautomatic is sensitive to cartridges, and stories about jammed actions because of insufficiently powerful rounds are numerous. Revolvers do not jam. If a revolver misfires or a case is underpowered, the shooter simply pulls the trigger again. The complexity of a semi-auto's mechanics compared to a revolver gives the revolver an edge in durability. A revolver can take a great deal of punishment and still shoot a tight group. The final point in favor of revolvers is their ability to accept powerful loads.
No semiautos can withstand the power of loads such as .454 Casull or .475 Linebaugh. In short, revolvers still rock!.
