I find it difficult to believe that so many people don't know that all handguns are pistols and are divided into the major subcategories of revolvers and semi-auto.
To the question, I own both but prefer a semi-auto for a couple of reasons; they are more accurate than revolvers, the average lifespan of a revolver is 50-55,000 rounds compared to 300-400,000 rounds for a semi-auto like a Glock and a lot of the recoil on a semi-auto is taken up by the recoil spring whereas all the recoil from a revolver goes straight to a shooter.
But, to each his own. Shoot and enjoy.
